Homebrew 6809 Computer: Plasma Effect

Old school plasma effect. ☮‿☮ The video chip only supports 15 colors, but with some dithering you can get pretty smooth results.

The video quality is crappy because of my capture device does not like the dithering. Here's a screenshot from the emulator: http://twitpic.com/4xektx

Technical info: it's Graphics Mode I, so computations are done per tile, not per pixel. The tiles have various dither patterns to simulate smooth fades between colors.
