See the link. You'd be sitting on the bottom blue ball. You'd both swing and push yourself up when you were close to the ground.

Congratulations. (+)

You sir have, after several generations of innovative stagnancy, have reinvented and made the Jolly-Jumper cool again.

Thanks, I couldn’t remember the name or find a picture of that thing. I kept coming back to the inverted version, the spring-mounted horsey rides at playgrounds.

//Jolly-Jumper//

Well, the Jolly jumper is just the spring, this adds a pivot to it. The spring isn't very chaotic, there's just two paths, up and down swinging on a pivot. This adds another movement element that multiplies the various movements quite a bit. The Jolly Jumper doesn't whip you around at random like this would.

See the Jolly Jumper animation for comparison.

But I'll take the slow clap.

Oh, hell yeah. Adding a [+] for [8th] who cannot be here.

Ahh 8th, he would have pointed out the whiplash injuries this design would cause and thrown up an enthusiastic bun.
