>>11732891It's a movie, well apparently more a documentary. And it's also at the heart of this magic square. For clarity, that magic book was strictly about card tricks, sleigh of hand, stage magic, some mentalism, etc... Now that i think of it, it wasn't in that magic book, it was in one called 'Board games to pass the time' and it had a section with jokes and a short section with a few magic tricks, one of them was this magic square. It had something to do with guessing what the audience had in mind, but the trick was possible with the use of the square. I'll see if i can find the book next time i get the chance.
