The Mengenlehreuhr (German for “Set Theory Clock“) or Berlin-Uhr (“Berlin Clock”) is the first public clock in the world that tells the time by means of illuminated, coloured fields, for which it entered the Guinness Book of Records upon its installation on 17 June 1975. Commissioned by the Senate of Berlin and designed by Dieter Binninger, the original full-sized Mengenlehreuhr was originally located at the Kurfürstendamm on the corner with Uhlandstraße. After the Senate decommissioned it in 1995, the clock was relocated to a site in Budapester Straße in front of Europa-Center, where it stands today.

The clock was referenced by US Artist Jim Sanborn in an online group attempting to code Sanborn’s final message on Kryptos before the artist’s death in 1990. The message remains unsolved.
Mention of the clock is contained in the FBI Dossier of The Family, and was scrawled in painted graffiti on the side of The First and Last Chance Cafe in Oakland California the morning of the disappearance of Canadian writer Darren Greer
