Earlier quoted context omitted.

You can see it so just that at the very end. If you look closely the plate itself is also spinning.

I don't think this is correct. The plate is moving atop whatever padding that is below it, yes, but none of the scratch marks visible on the surface of the platter appear to be rotating as the person moves about it.

I looked at the youtube video closely, it's only 1080 though, I also don't think it is spinning. You can hear the tubes grinding against the plate.

NASA has a much lower tech solution at Cape Kennedy: it's a wall that is slightly off vertical. You are strapped into a harness and lifted off the ground so your body is horizontal and your feet rest on the wall. The angles are calculated so the force of your feet against the wall is the same as the gravity on the moon, while the strictly vertical component of your weight is supported by the harness. The net effect i…

Yeah, like this (Russian narration, oddly): https://youtu.be/17vY8r84NCA

I mean, that sounds cool and would allow more freedom of motion for a more realistic moon walk, but I don't know if I'd call that lower tech. This thing seems to be a small elegant and easy to transport counterweight. I suspect moving the NASA setup would be difficult :)

Colin Furze did it a year ago. https://youtu.be/gSDtNkKPiDg And wires with counter weights have been used in movies since forever.

As annacappa noted, this predates Colin Furze's (which was awesome and totally worth a watch), but it's a much simpler design than Furze's or movie wire walking. 'course, you can't go as high. But good for a small performance. And actually, I think comparing it to Furze's there's more potential for freedom of movement in various directions, although Furze did have that retraction mechanism in his arm, this one seems like it allows moving the entire piece around the room due to the simplicity of it.

It's usually harder to take a wall with you for performances and what not?

I looked up the thing you're talking about, the artist's device is way cooler IMO.

> “The net effect is that walking and jumping on the wall is the same as walking or jumping on the moon.”

Anyone try it after actually being on the moon?
