Hi there,
Yup, truth be told, I am a fan of the 1974 game show, "Now You See It." So, if there is a Mac version of the game (or if there's a game similar to its 1974-75 gameplay), please let me know where I can find it. In 1990, A company called GameTek made an MS-DOS version of it but, obviously, that may be a bit hard to play on a Mac.
For a brush-up, here's the Wikipedia link to "Now You See It":
