Atari-esque 1-bit AVR synth

This is a simple 1-bit synthesizer made in a few hours with just an ATmega168 and practically no external components. One potentiometer controls frequency and another selects one of 32 waveforms. (They're actually 16-bit patterns.) This is the same technique used by the Atari 2600.

The waveform and frequency are shown on an alphanumeric LED display I made myself (see http://www.youtube.com/watch?v=Eg46EFM--GU). The audio is played through my monitor's speakers and is shown on a Tek 464 scope.

My camera is dying, which is why the colors look creepy. I'll try to get better quality audio up in the future.
