Underabove Twin Camera

The UNDERABOVE floats like a buoy thanks to a pair of watertight ballast compartments, takes images with twin cameras above and below, and unites sea and sky. Then stitches the result into a turquoise vertical panorama viewable on the inbuilt LCD screen.

If and when this device actually gets produced (and gains some serious image stabilization) the worlds of fish and man will never be the same.  via engadget
