That took 600 hours to construct? There are several clearly inefficient operations. That video should be called, "waste of electricity."

I liked the parts where a basketball hoop was involved!  Quite the contraption.

Me too. I wish they had devised a way to weed out the balls that did not go in. Or perhaps they could have only accepted basketballs past that point.

Actually, I think the balls that do not go through the hoop on the first shot slide back to one of the three shooting gizmos and are shot again.  Only after they go through the hoop can they continue.  One of the greatest challenges may have been to match the throughput of each section (1 ball per second) so the balls do not pile up somewhere.

I think 600 hours is time well spent considering the awesomeness of the display (and he won't have any problem getting job offers in manufacturing automation).

I was thinking of the second hoop. You're right about the first.
