Two really fascinating videos that tackle related ideas.
They make me a little queasy but I'm fascinated by them.
The first one is a GoPro camera attached to a hula hoop.
The second one is a bit more complex. Callum Cooper, the filmmaker, built a rig to mimic a jumprope. At least I think that's what's going on here. He has some more twisted pieces as well on his Vimeo page.
