My wife got me a Pentax digital WG-1 P&S for Christmas that, of course, shoots video as well as stills; she thought we could use it around the water. (It is supposed to be waterproof to 10 meters, but as a diver I'm not convinced.) This is a little video that I put together of us taking our daughter to the bus for her ride back to school in Chicago (Evanston, actually).
