Some of you might remember the famous blinkenlights installations of the CCC in Berlin at Alexanderplatz some years back. Basically they used a matrix of windows on a building for a low-resolution display to play pong and display all kinds of animations and text.
After a long break, they're back, even bigger with blinkenlights stereoscope, a massive installation spanning 960 windows of Toronto City Hall. The entire backend technology has been re-implemented based on OpenBeacon , specifically the WMCU and the WDIM units.
