Camcorder Clock
If you happen to be paranoid about leaving your office unprotected, or you just have a love for spy-style gadgets, the Camcorder Clock ($200) is for you. It features a motion-activated color camera that can capture up to 12 minutes of video on its internal memory, or expand the memory with an SD card. It outputs 320x240 AVI video that can be downloaded directly from the card or from the clock via USB, so you'll never have to worry about anonymous office pranks again.
