I have always wanted to learn to scuba dive. The chances of me ever getting my wife under water after seeing that flick Open Water is slim to none though. The best I can hope for is that someone I know goes diving and uses a mask like the Liquid Image Model 312 mask.
The mask has a video camera built in that records at 30 fps in 720 x 480 resolution. The camera can also shoot 5MP still images and operates down to a depth of 65 feet. The buttons are large and designed to be used with gloves.
