I want to second Byte's note of thanks. Today I finished setting up a pole which will hold an A2000 11 feet in the air within a weather-proof box for a year (fingers crossed) to record a time lapse construction progress of my organization's new building using the intervalometer script. If it wasn't for the existence of CHDK, what I'm doing would not be possible without a big investment in more esoteric equipment. So Canon has CHDK to thank for the purchase of another camera.
Thanks for everyone's hard work on CHDK!
