Reality Hacking No. 140, City Hall, Zurich, Switzerland, 1 April – 17 May 1998
In each tunnel under Zurich‘s City Hall manipulated traffic lights were installed. The lamps in the 2 tunnels were connected and blinked every night from 6:00pm to 6:00am in a changing left/right pattern, as if the light could jump from tunnel to tunnel.
