This generative public art installation was assigned to us by Abalos & Herreros, architects of the Barcelona Urban Waste Treatment Plant, which was the main facade of the Forum de las Culturas de Barcelona in 2004. It seemed interesting to use the opportunity of the large waste treatment machine to produce a prototype of a new contemporary façade that would interact with people and allow them dialogue in a public space. Visitors to the Forum de las Culturas could write messages with their mobile phones live, in a size of 55×16 meters, which made them a public mode of communication. Another board would be located in the moving urban landscape that constitutes the Barcelona ring-road, providing a fleeting show to thousands of drivers: 440 blue LED bulbs would serve to monitor the plant’s sensors, making visible environmental data related to their own garbage to the citizens of Barcelona or any other type of information in a graphic, fast and intuitive way or even retransmissions of the sea that is behind, blocked by the same Waste Treatment Plant that serves as support thus becoming sort of a huge X-ray screen.
