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.
