About Set Theory Clock (BerlinClock)
The Berlin Clock consists of 24 lamps arranged in 4 rows. The top two rows (red) represent the hours, and the bottom two rows (yellow) represent the minutes. Additionally, a circular yellow lamp at the top flashes every 2 seconds. In the top rows of each color, each lamp represents 5 hours or 5 minutes, respectively, while in the bottom rows, each represents 1 hour or 1 minute. The lamps light up from left to right and from bottom to top. Once a row is full, all lamps turn off and another lamp lights up in the row above it.
