If you've always wanted to wear your camera while swimming, rollerblading, or skiing, this is the one for you -- a waterproof digital wrist camera from ThinkGeek.

It's a three megapixel camera, weighing in at 3 ounces and able to take still images in three-shot bursts or video footage at 30fps. You get 16MB of on-board memory, which can be extended via SD card, and the whole thing is powered by 2x AAA batteries.

If you're taking it for a dive, beware that it's good up to 100 feet. Here's a photo I took with it while surfing (yeah, right.)
