Holy crap, now that one I have not seen.

The ones that I was talking about were carbon fiber/mylar. Not too sure what that one is made of, but its definitely something that I haven't seen. Probably costs a pretty penny for all of the components as well.

Aviation Week did an article on this several years back. DARPA actually had one that was and ornithopter, (flaps wing like a bird!) The speculation was that this vehcile would be covered with feathers to look like a pigeon. Imagine, a pigeon landing on an embassy window! No big thing! But one heck of a spy device!

DARPA mentioned that the MEMs (micro electrical machines) would power these devices and a BUG might really be a "bug". My link to the DARPA site shows a bumble bee sized device! wakka wakka!
