an impressive interactive full-building facade on a 145m high tower in Brussels (Dexia Tower, Belgium), on which 4200 windows can be individually illuminated by RGB-colored LED bars.

at the bottom of the tower, an installation allows people to interact with the visual tower display via a multi-touch screen. both static (touch) as dynamic (gesture) input is recognized to generate an abstract graphical language consisting of points, lines & surfaces combined with physical behaviors (growth, weight, ...). once a composition is created, a live snapshot picture, taken from a distant location, can be sent as an electronic postcard.

ideal end-of-year decoration.
