Each panel of the sculpture presented a different live feed, from transport information from TFL, environmental data from CASA, to live energy usage from Carbon Culture. The feeds were visualised by a network of over 30 volunteer coders, using a toolkit developed by Matt Pearson for the project.
Prism was installed in the tallest tower of the V&A by Millimetre, a space opened to the public for the first time for the installation. Visitors were guided up a tight spiral staircase into the exhibition space, and then up onto the roof of the tower for a spectacular view over London. This juxtaposition allowed visitors to see both the physical and virtual views of the city, stacked on top of one another.
