Split-flap clock

The split-flap display, or Solari board, once showed departures at every airport and railway station. This online split-flap clock brings it back: each character is a stack of flaps that flips through the alphabet until it lands on the right one.

The time sits on the top row with the date in yellow below. Change the flap and character colours or the font to match your setup.
