An Oscilloscope Clock

Using a three inch oscilloscope tube as an X-Y vector graphics display allows creating an elegant clock that even plays Pong and Tetris. It is available in limited quantities and “as available” delivery times in either kit or assembled form from Cathode Corner, which also sells two models of Nixie tube watches.

If you prefer to roll your own, complete schematics (pages 1, 2) are available as well as Arduino source code for the firmware from GitHub.
