Canon Hackers Development Kit.

I have a Canon S90 P&S and just tried out the CHDK firmware upgrade for it, went from 15 seconds maximum shutter to basically unlimited, I've taken 20 minute exposures already.
CHDK adds the ability to script your exposures to automatically do time lapse photography, focus bracketing and HDR bracketing. Also adds the ability to use a simple USB remote trigger for your camera and to synchronize two identical Canon P&S cameras for taking stereo photographs and adds a motion detection trigger that's fast enough to capture lightning. One more thing, CHDK allows the use of RAW files on many Canon P&S cameras that don't have that as part of the stock firmware.

CHDK also allows very high shutter speeds, up to 1/60,000 of a second, here's some interesting water splash photos taken at very high shutter speeds with a hacked Canon.

And here's someone using the motion detection trigger function to capture images of lightning.

The nearly full Moon is off to the right which is why the right side is washed out, the sky was so bright from it I couldn't open the lens up enough to get good star trails, I'm going to try again a week or so when the Moon is out of sky for at least some of the night.
