A few years ago I watched some kind of Japanese patience / endurance challenge.
I don’t think it was the gameshow endurance.
On this one, contestants had 3 or 4 dice stacked on a spatula. They then needed to work this spatula through a long series of really fiddly structures without dropping any dice. If they dropped the dice, they’d have to go back to the start, no matter how far through they had got.
Every now and then there’d be a caption saying e.g. “5 hours later…”
Anyone know what this is? I’ve spent almost as long trying to find it as they spent doing the challenge.
