I saw the first of these several years ago at a Spike and Mike screening. No surprise somebody would put them on YouTube.
BTW, I remember when I was a kid in the 1970s, I used to watch a chess show on PBS. Not because I was trying to learn. I just liked watching the animation that made the chess pieces look like they were moving on their own (nylon wires, I suppose). Anyone else remember that show and what it was called?
