New videos, last week(s)!

Little by little we are getting really high-quality video for the City of Science video contest. It is very gratifying to see how each contestant provides a different look of their environment. However, this look is always accompanied by a touch of science. We sincerely thank all the participants for their contributions and remind those who want to participate, but have not yet uploaded any video, that the deadline is getting closer. The deadline is June 30 for videos in Catalan, Spanish, English and any other language other than French. French videos can be uploaded until July 19. Enjoy science and your city!! For those who participate in the contest good luck!!

Here you can see some of the new videos…


Ideation and creation of scientific videos Workshop at Santa Monica Arts Center

Science of the City promotes a different view of what science is and where you can find it in a city. Science of the City encourages participants to make a two minutes video relating science and cities. Videos can be a question, a finding or a scientific experiment. These videos will participate in an international competition with 8 different prizes.

We have organised an ideation and creation workshop, tomorrow 22nd of june at 4pm at Arts Santa Mònica. During this workshop we will propose questions and experiments and look for places where you can shoot your videos. We will sketch the script and start filming. You can bring your cell phone camera or your own camera.

You do not need any prior knowledge on science or video, but if you want to join us, please confirm your attendance by emailing See you there!


Science of the City, opening its own website!

The “Science of the City” project continues encouraging citizens around the world to look for science that lurks in the corners of their cities and putting it on a 2 minutes video. This was published at El Tercer Milenio from the Heraldo de Aragón newspaper.

More and more institutions, museums and universities are adding efforts to contribute to the promotion of this project. Currently, we have the support of The Tech Museum that sponsors seven awards, Arts Santa Mònica, Trànsit Projectes, the Observatori de la Comunicació Científica de la Universitat Pompeu Fabra, the Museu de Ciències Naturals de Barcelona, Singapore Science Center, Liberty Science Center, Biobus, NY Hall of Science, The NY Academy of Sciences and Paris-Montagne. Wiser-U will also sponsor the best French video award. So for now, you can participate in English, Spanish and French.

In addition, we have announced the project site. You can find it at We hope you like it and  we encourage you to use your holidays to make a science video in your city or in your holiday destination city!

We are also in Facebook!

The “Science of the City” video contest starts today!!

Today officially starts the “Science of the City Video Contest“.  You can find more information at The Tech Virtual new website.

Look at your city with a different perspective. This time, instead  of searching for shops, streets and restaurants, look for scientific finding: snails, fossils, LED, chemical reactions, etc.  Think about a scientific experiment and test it in your city: Newton’s laws, fluids laws, chemistry laws… Or make yourself a question! These are the three categories of this video contest:

Once you have chosen a topic, you can make observations, wonder, get information, run an experiment, use your imagination or ask us. Finally, you can create a 2 minutes video and upload it to “Science of the City“. You can win one of the 7 prizes offered!

We will build an exhibition with the better and most voted videos and with the tags you use.  Do not hesitate and enjoy the experience of creating a different, freak, creative, imaginative, funny video. You can be part of a collective scientific exhibition!

The contest starts now and it will last three months. We will announce regular meetings to co-create the most scientific and original videos ever seen!!

Keep in contact!!


Proposals night

Tonight has been very active, almost looked like the Christmas night. We woke up, and there were 5 new proposals that filled the projects folder on the website at the Tech Museum. We will briefly describe and explain them to you and we’ll continue working in order to have everything ready to start voting today from 22 pm on, local time in Barcelona.

Memory Launch

Memory Launch is an installation that suggests sending memories in video or photo format from any place in Citilab to the  friends of the visitors. These friends  are in different places, outside  Citilab.

The Internet has changed the way we share memories in that we can almost “transmit” them to people who are far away. Memories are shared by photo and video but also by souvenirs… Send them to your friends (or to home) from this cube! How does this change the notion of memory versus what it is happening now?

These ideas was proposed by Kyle Walker.

Message Modes

This cube explores and tests the experience of three different types of communication. It allows visitors to send messages to someone else on the other side of the cube by using three means: writing, chat, and videoconferencing. Visitors can observe and enjoy their experiences using these types of communication. Which one is faster? Is there any difference in how we communicate using a medium or another?

This proposal was made by Bob Ketner.

Dynamic Docuverse

The “docuverse” is a concept that was coined by Ted Nelson in 1974 when he conceptualized the Internet as a centralised source of information. Now, the Internet allows documents to be  changing forever, and many versions of a document may exist across the Internet.  Besides that, documents themselves change as we edit them in multi-user platforms. The Internet now allows us to have such  documents that  are aso dynamic that the concept of what a document is is put into question. This cube discusses how  collaborating on a document in real time changes our conception of documents in general.

This proposal was made by Bob Ketner.

The world is flat

On a computer screen, the world is flat. It is in this flat world where people connect and visit various places through videos, images, text, etc… In this module the visitor can use four touchscreens. Each screen offers him or her several options: Google Earth, Google Images, YouTube and a webcam, and visitors are free to travel in two dimensions around this flat world and share it with others.

This proposal belongs to Huodig Nguyen.

Future workspace

This installation represents a preview of a workstation of the future. It shows how different employees will use the same window. Each table will have a set of screens placed in a circle and so people will be able to work in different projects.

This was one of the first proposals, which has finally been documented  by Daffodil Yuhara.

Tonight you will be able to vote!

You see, this is a box of surprises! Stay in touch with us and we look forward to receive your votes on-line or accompanying us tomorrow, Thursday April, the 8 starting at 17h, in Citilab. Remember that at 18:30 pm (local time in Barcelona) we will close the votes space,  so do not miss it!


The proposals are getting ready to be voted!!

Easter Holidays ended, and with them, the deadline for submitting designs to the first exhibition organized by the Expolab project. For nearly two months, designers and fans around the world have contributed their ideas and suggestions via the Web and Second Life in the virtual space Citilab has built within the Tech Virtual Museum of California island on Second Life. So far, we have collected ten complete proposals which include the design and full description of the corresponding idea and its realization. We also received six other proposals that  are still in the making.

This post wants to share with you all of them as a warming up for the voting day. The vote will take place on April  8th. We’ll wait for your at 5 pm at the Citilab entrance hall. Try not to miss the drinks and the atmosphere we will enjoy in this meeting!. However. if you cannot make it, and  as we want to leave no one out, you will always be allowed to vote online! (We’ll tell you soon how you can do that).

Proposals of the participants

Bank of Ideas

Contributed by Bob Ketner. It represents a large bowl full numbered cards, each with its own text and image corresponding to an idea. Visitors take a card from the bowl and suggest a new proposal and they give it the same number of the corresponding image or text. Each new proposal will become part of the bowl.  In that way, all the initial ideas of the initial proposals will evolve towards  new suggestions. The original numbering of ideas is maintained in order to be able to track the evolution of ideas. This cube is intended to analyze what are links like, that is, how the links on the internet help us make our thinking evolve.

This is the analogic part of the proposal. The digital counterpart will be worked through and through by using Twitter hashtags, i.e, small sets of letters preceded by the symbol “#” that are used to identify tweets  related to a specific topic.

What’s your point of view about security?

This cube is made by Marie and Stephen Crandell. It analyzes the visitors’ feelings of security in relation to past and present times. It proposes the creation of two rooms within the cube. In one of them there will be a figure representing the old “serenos” (night watchmen). There will also be a person who would open the door for you. This person is allowed to enter and leave the cube whenver she or he wills. In a second room, a CCTV camera would be installed and show its images in another part of the exhibition.

On the outer part of this cube, a white wall would encourage visitors to use graffittis to explain how they have felt while inside the cube. In particular, they will be invited to commento on which of the two experiences made them feel better (the person sneaking in side every now and then or being watched by a CCTV camera). The remaining outer walls of the cube would be used to explain how CCTV cameras work and what is their history. They also would be used to show the tweets of all those who participate in the exhibition. In that way, the boundaries of the exhibition would be pushed. This cube also propose to use some kind of hashtag (such as #cctv, for example) and to encourage anyone who has seen or come across a CCTV camera in any place to use a tweet with that hashtag to tell the rest of the wolrd where the camera was located and how he or she has felt about it. So, visitors themselves would be watching the cameras around.


This proposal is designed with the help and support of Maria Bobes. It discusses the connections between people and social networks. These concepts are represented by two walls. On one of them the relationships that the visitors hold with other people would slowly add up by means of threads of different colours and textures tied up by visitors. On the other wall, they would be asked about how many “strong” and “weak” relationships they can maintain.

Pin Analog Scanner

This proposal was contributed by Philip Dolman. It explores the world of work and globalization in the fields of design and construction. It is an interactive illustration of the globalization of design.  It proposes to build a cloud of points for each visitor who approaches the cube, digitize it and build a small object from the resulting digitization.

This proposal seems quite interesting … but what challenge to build it! Let’s see how it evolves!

Social Networks

This design was made with support of Lars Stalling. On the inner part of the cube a video is shown in order to observe interactions between people. This video can be made in a participatory fashion. In fact, it would be possible to offer workshops in order to train people to make the recordings and to create videos. In this way, the visitors would end up modeling the  scene showed on the cube.

On the outer walls of the cube the science behind networks would be explained: types, structure, evolution … and  much more more!

Digital Skies

Charming proposal from Bob Ketner. It analyzes travel through space and time in the Internet era. It   creates an insulated cube where visitors are asked to enter data about the place where they would like to travel and also its time zone. A screen would display images of the chosen location and the  lighting system would simulate the amount of sunlight or darkness in the chosen area. If at the time of visiting the exhibiton it were night time at the selected city, you could see on the cube’s ceiling   all the stars in this region at this time of the year. So, one would recreate a live global travel experience.

Although the visitor actually performing the virtual travel would be isolated from the outer side of the cube, other visitors on the outside of it would be able to see what was happening in the inside by means of, for example, the use of polarized glass

Thanks to this exhibition it would be possible to get Citilab and the Tech Museum more connected.

Sharing memories: photography

This cube was developed by the Expolab team at Citilab. Its origin comes from one of the anecdotes that were told during the Expo-design workshops.  It analyzes the evolution from analog to digital cameras and its associated social impact. In the past, we only had a couple of pictures that were highly significant to us, whereas now, we have a thousand pictures of every corner. The photo developing process, based on chemical products, imposed physical constraints that prevented the excessive manipulation of photographs. Now, however, the use of semiconductors and the translation of light into ones and zeros, i.e., into the language of computers, allows us to manipulate that information easily.

Within this cube the basic operation of a camera is also shown. A set of lenses that is used both by analog and digital cameras is also on display and the construction of a stenopeic camera is proposed.  We encourage visitors to upload their photos via Flickr to share them with the rest of the public.

A shrinking world, growing connections

This contribution is made by Rob Stephenson. It represents a map of the social network of a person before and after the Internet. It uses a globe to encourage visitors to map their friends and acquaintances around the world. It invites us to reflect about where were the people with whom we were related before Internet.

The Evolution of Social Networks

This proposal has been designed by Jason Spriggs, a contributor under 18, and also a member of the Teed Greed. Jason wants to talk about how social networks started with the neighbors and have become a business.

The Introductory cube

This cube has been codesigned by the Citilab-Expolab and Tech Tech Virtual Museum teams. We are still working to create an introductory cube that will display the whole process by which this exhibition has been made. We also will  and where we will invite visitors to recommend visit itineraries to new visitors.

The image we have is still a sketch that must be improved so that visitors can get to know every person that  has been involved in the creation of the first Expolab exhibition, which are many! Also we want to share with visitors the images of all the prototypes that were created in the process and all the good ideas that have been generated, since all that material is Creative Commons. Last but not least, we don’t want to create a cube where only the voice of the organizing team is heard, and that’s why the visiting recommendations are left to participation.

These are the proposals that have been more thouroughly developed. However, all along the co-design sessions and meetings in Second Life other prototypes have been created. These ideas and prototypes could be finally completed and en up making their way to the final exhibition if you vote for them.   We don’t want to leave any idea out of your scrutiny!

So here you have them too:

Travel in time and space thanks to the Internet

Instantaneousness: travel in time and space


Evolution of Social Networks II


Other proposals

We appreciate your feedback on this blog … We also encourage you to come to Citilab on April 8th , 5 pm, to vote the proposals that you liked the most! Do not miss the opportunity to participate in this first exhibition of Expolab, a new way of understanding the exhibitions that opens them to the public! Come on, join us, tell us your opinion!


The expo-design workshop, the preceding of the Second Life contest

Expolab team is already working on the management of the design competition in Second Life organized in collaboration with the Tech Museum of California, and in fact, the contest began a few days ago. They have appeared the first designers to show their interest in the project and we are following the whole process to see if we can start to show you some results.

For now, we want to share with you the video of the expo-design workshop we did here in Citilab, on January the 14th. From this meeting, along with a couple of work sessions done previously, we have selected the topics and the design proposal for the design competition that is being proposed in Second Life. You can’t miss it, these are the origins of the first Expolab’s exhibitions!
