I looked up the thing you're talking about, the artist's device is way cooler IMO.
Anyone try it after actually being on the moon?
And wires with counter weights have been used in movies since forever.
The body harness isn't shown but it looks jury-rigged and bulky. There are a variety of low profile harnesses designed for stunt performers doing wire work which could be adapted. I also wondered about reducing friction at the ground plate through flattening the bottom side of the pipes and polishing both surfaces. Applying teflon sheet and/or a light coat of lubricant might further enable substantial rotational velocity to be built up. Perhaps giving the top of the ground plate a slight bowl shape would help keep the pivot point centered at higher speeds.
I think there's a lot of interesting potential with the concept and I hope this artist or others continue to explore it.
It does look like it would be pretty easy to make with just some bent metal and exercise weights. Colin Furze's one worked well too, maybe this 'invention' was influenced by his. There are many of these on youtube, some years old.
