>>There's no "starting point" and there's no need to look at the Cube once you've memorized the sequence of moves. All you need to know is left from right, up from down, clockwise from counterclockwise, and how to count to at least three.<<

You must keep in mind, for example, that the center tile on each face of the cube is the color of that cube face when the puzzle is solved.   That 180 degree turns are the same whether clockwise or counterclockwise. And so on. You practice it, you'll simply memorize the moves. This guy does it by feel. His cube appears to be notched or indented on the tiles if you look closely. He feels those and organizes them accordingly. You see him almost forget where he was at. Blindfolded Cube competition is real. This guy isn't cheating, it's simply how he plays the cube. He can't do it by sight. I think he may even be Tyson Mao, not sure.
