Thanks, Dan for pointing out that I didn't explain this well. I also 
hope you don't mind me quoting this snippet to the list. What I mean is 
in both videos the ATM rotates the bottom AND top together in one 
direction, then rotates the top piece BACK in the opposite direction, so 
the top glass is in (almost) the same orientation it was before rotation.

It IS OK to turn the pieces in opposite directions, as long as you turn 
them independently, so you are not pushing along the same chord of 
either piece.

Sorry for the confusion. Hope that clears things up.
