Very cool! The Passing the Cup and Energy Ball are my two favorites.
My wife and I tried the clone where we were going to clone two of my wife but I could not get it to turn out good at all. I think it was because of the low lighting we had because we were trying to do it in the evening time outside. By the time we got the other footage shot one video would be a little darker than the other because the sun went down some (I didn't think about that at the time we were shooting, but know now!

). It was our first time trying too, because we are new at this ourselves. But it did look pretty neat though otherwise.
Great Job!
