A great hand and foot powered merry-go-round. This one is in a park in the small town of Hyndman, PA, near Cumberland, MD.
[Note: as of Feb 2012 it has disappeared--don't know if it's permanently gone, or just out for repairs!]
Took some pictures of this with a view of getting someone to make me one someday. Anyone has plans, let me know!
I know they were originally sold by GameTime playground equipment, but they of course no longer make them, and I've been unable to locate the original patent or drawings.

Seems to me that the folks promoting "PlayPumps"--merry-go-round water pumps for the developing world--ought to look into this design rather than the ones kids run around and push. Of course, it appears the project has been cancelled now--it appears that dying from dysentery or thirst is deemed better than getting a skinned knee from playing on a merry-go-round.
