GBC Loop Upside down

[Diamabolo]

further development of my endless ball track to a gbc loop

There is a hypnotic quality to this. I wonder if you could tweak it such that the average rate at which the ball falls is matched to the speed of the track so that you only have the moving track.

I just saw your previous post where that's what you had (I think). Very nice!
