So three states... does that make fading up/down out of the question? You could come up with some interesting visuals if you can fade between your three colors. Have them all cycle green up/down, amber up/down, red up/down... all at different rates and intervals. It could be all throbbing...
I mean I guess the way to do a fade would be to flash it at increasing rates (to fade up) and slow down the flash to fade down... And there's all kinds of patterns that fit in that size. a horizontal spiral... a zig-zag Anyone see the radiohead concerts? They had a cool rig on stage behind them that did some fun stuff.

A friend of mine used to have a cool PPP server that didn't work, but it had all these LEDs that blinked in fascinating patterns when you put it in diagnostic mode. We just left it on all the time, by the TV. Heh. It was more interesting to watch, usually. But I wax nostalgic. j
