Berlin Clock Opera Widget: Track Time Style The Berlin Clock, also known as the Mengenlehreuhr (set-theory clock), is famous for its unique way of telling time using colored lights. Instead of traditional hands or digits, it uses rows of glowing red and yellow bars to represent hours and minutes. Bringing this iconic piece of German design to your desktop or mobile browser is easy with the Berlin Clock Opera Widget. This extension combines historical mid-century styling with modern digital convenience. What Is the Berlin Clock?
Designed by Dieter Binninger in 1975, the original Berlin Clock stands as a landmark in Berlin-Charlottenburg. It tells time by calculating a series of lights based on a base-five system. Top Round Light: Blinks every two seconds. First Row (Red): Each of the four bars represents 5 hours. Second Row (Red): Each of the four bars represents 1 hour.
Third Row (Yellow/Red): Eleven bars representing 5 minutes each (the 3rd, 6th, and 9th bars are red to show fifteen, thirty, and forty-five minutes).
Fourth Row (Yellow): Each of the four bars represents 1 hour.
To read the clock, you simply add the values of the lit bars together. Why Choose the Opera Widget?
