One one level, these autonomous robotic jelly fish illuminated the
mechanism by which real jellyfish swim. Two kinds have been invented:
one type that swims in water and one (shown in the video) that swims in
air, via a small helium bladder. The parallels in their motions --
clearly visible in the video -- feel so organic that we immediately
assign them life-like adjectives.
