Hobie uses that system in the their pedal powered kayak. The flippers only move in one axis and rely on thier flexing to provide the thrust. I would guess they move through 80 degrees of motion. The video looks to have a very complex motion through multiple axis. One advantage of the Hobie system is that you can short stroke the fins at the end of their travel to traverse very shallow water.
Interesting, either way.
