crazy die Idee, aber witzig allemal:
Colour by Numbers is a 72 meters high light installation at Telefonplan in Stockholm, Sweden. You select the floors you wish to colour using the buttons 0 to 9 on your phone. The various combinations of red, green and blue can be selected on the keypad. The tower can be monitored via live video feed on the net.
Dat kann man sich auch live anschauen.
