The Digital Hero Waterproof Wrist Camera is basically what it sounds like: a waterproof digital camera that you can wear on your wrist. We've always wanted one of those!
It retails for about $80 and can store 360 low-res photos. The manufacturer recommends it for underwater exploits up to 30 feet deep, as well as surfing and skiing. There's even a self-timer and a few other bells and whistles, so that you may be sufficiently distracted while snorkeling as a barracuda heads straight for your jugular.
For something slightly less obnoxious, consider the Casio Camera Watch.
