This one is very interesting. New to me, at least. From the PopSci writeup:

"AeroVironment showed off prototypes of its nano air vehicle, a hummingbird–sized flapping-wing UAV that one day could be used as a surveillance tool that blends into the natural environment."

I wouldn't mind having a couple of those fuel cells. I wonder what they cost/weigh.
