I just remembered 3-D chess from Star Trek with Spock. I remember a kid he beat used mental powers to melt a piece
Also an episode where Spock proves the ship's computers were tampered with because he was able to beat the computer at chess - a program he wrote himself!
(the guy who melted the pieces was Charles - a kid they picked up on another planet who had mental powers and was just learning how to handle stress.)
CGI short from pixar b4, I believe, toy story?
That is actually at the beginning of A Bug's Life. I don't recall the name of the short film, but it is fantastic.
