I attempted to do something like this the day before yesterday, but I was gonna use a NBN ball to play bowling.

Wait, that could be your Future robotics recycling on-line challenge entry! But you may have to share with antichamber, since he was frist psot here. And he has a jpeg showing the pyramid.
