Believe it or not, the object in this photo is a clock. It's called the Mengenlehreur and can be found in Berlin. The yellow light at the top blinks, showing the seconds. The top row shows the hours. The bottom row shows the minutes.
This is 1 of 11 unusual clocks in public places rounded up by Atlas Obscura. They include a sandglass that takes a full year to flow and an animatronic clock in Dubai designed 900 years ago.
