Pong clock plays one round of Pong every 60 secs

The Pong Clock from Buro Vormkrijgers plays games of Pong that last for exactly one minute each, with alternating sides winning. The clock in the middle keeps time/score.

Update: Hijinx Comics sez, "It actually scores the time, with
the left side only scoring once per hour and the right scoring every
minute."
