OK so this is super slick. If you watch real close a few times you'll see he's doing the same movements every time. So he's not really "solving" them… they were set up to be solved. It's still pretty impressive though given the dexterity to do either.
technically they are all set up to be solved. its all figuring out where the pieces you want are and "doing an algorithm"

even if he has them preset, it takes a lot of control to be able to get them to fall into your hands right so you can make the correct move in time and be sure you are able to remember which move you need to make on which cube next.
Totally agreed. I wasn't trying to diminish the difficulty of what he's doing. Only that it is in fact different than a totally scrambled cube.
