A more fun design would be a projector.  Scan a laser pointer by
spinning it fast and modulate the beam so that it looks like a few red
dots on whatever screen it is aimed at.  Maybe salvage the scanner
mirror from an old laser printer.

The LED based design would be easier but less interesting, just some
7400 series chips, some LEDs and a small uP.
