Also, our latest Voicebox theme, uses a 'physical data visualisation'. We want to create a portrait of what young people care about, so they submit their 'cares' to us and a robot - the Voicebot - writes them out in real time, in the real world, with a pen, inside the Houses of Parliament for MPs to read! This project is live now. You can see the livestream http://www.vinspired.com/voicebox.
We were interested in not just collecting data but doing stuff with it as well i.e. sharing it with the people who make decisions, actually in the corridors of power. Using the Voicebot, "data" becomes something that we collect and then distribute in an environment where it can be used.
