I don’t know what you would call this but essentially this juggler is able to solve the Rubik’s cube while juggling. Perhaps Rubik’s Cubbling (cube-ling).
Anyway, it’s pretty cool. Check it out.
When I was a kid I was really into the Rubik’s cube and learned how to solve it. I can still do it but have never tried juggling while solving. Maybe that’s a trick worth learning.
