I never thought looking at underwater lava formations could be so mesmerizing. I could easily spend an hour or more looking at that. Half of it is just lure of the ocean, and half of it is just the coolness of watching a live feed of a underwater robot from the comfort of my den at 5:00 AM.<p>I wonder if that's a stereoscopic camera. The depth of field looks good, but I had a problem gauging distance several times. Some formations, viewed straight on, looked small until the robot came around for a side view and I realized they were much bigger than I thought.
