Waveform display on a VGA monitor with AVR

Not so useful, but nice: "Waveform display" (like a oscilloscope) on a VGA monitor.

It's a really simple circuit: ATTiny85, some RCs and VGA connector. (Not counting the pre-amplifier.) It displays a waveform of an audiosignal on a VGA monitor. The most interesting thing I've found is an information about timing and creating VGA signal in a tiny AVR with memory etc. restrictions.
