That's awesome. But from the last page of the patent, it looks like it was re-examined a month and a half later and all the claims were revoked.

- noonespecial 17y agoI'm pretty sure someone went to a playground and directly observed "skilled practitioners of the art" independently discovering the methods. I think there might have been some prior art on a few million 8mm film reels in people's attics as well... It would seem immediately apparent to most 2 handed children. I do find it interesting that the patent missed out on the method of elevating one's ass by pressing outward on both chains. Now that's technology.
