Well, the idea was to go with an ornithopter, which is a device that specifically uses flapping wings.
When I was a kid, I had one in the shape of a bird. You wound it up, threw it like a paper airplane, and watched it go like no paper airplane could.
This sort of thing really captures the imagination.
