Some glorious bastards have put together a hack package which allows low-end Canon PowerShot cameras to do some very nice things including time-lapse photography, motion detection, and USB control... http://chdk.wikia.com/wiki/CHDK Possible uses: Creating time-lapse backgrounds for Anonymous videos. A camera on tripod to record all the traffic in and out of an org for a few hours. Night sky time-lapse with a long exposure setting. If you have a different make of camera, it might be worth looking to see if there's a similar package for your camera. P.S. This is hacking in the old school sense, not techno-vandals. Nothing illegal about it.
