Project Blinkenlights was founded with the creation of Blinkenlights, the original interactive light installation that came to life on September 11, 2001 at Haus des Lehrers in Berlin, Germany.
The upper eight floors of the building were transformed in to a huge display by arranging 144 lamps behind the building's front windows. A computer controlled each of the lamps independently to produce a monochrome matrix of 18 times 8 pixels. During the night, a constantly growing number of animations could be seen. But there was an interactive component as well: you were able to play the old arcade classic Pong on the building using your mobile phone and you could place your own love letters on the screen as well. Blinkenlights was up and running at until February 23rd, 2002, running 23 weeks and 5 days in total. During that period, its feature set was constantly improved. The program Blinkenpaint enabled everybody to create animations and to take part in our animation contest. The software has been released as Free Software.
Building facade was used as an interaction tool in urban space.
