Another flying bicycle?

Actually this is a human powered heliocopter rather than a bicycle because there aren't any wheels.  This is a pretty awesome machine, rather different than you would expect (video at link).  There are 4 rotors, huge ones, at the cornvers of a square frame, and they move at a fairly leisurely rpm powered by a recombant bicycle power plant at the center.  It doesn't seem possible it flies.  This demonstrates that new materials let you design things in new ways.  Wow!
