neat and clean design. I love the rotation feature. splendid idea!

have you ever thought about replacing the three reminding movement buttons with motion sensors as well? I was wondering how it might look and feel to have a Tetris machine that can only be controlled by shaking it like crazy... and as you won't need any buttons no more, it could get enclosed in super clear epoxy...

but that's of course a whole different project.
