Ahh, actually now that I've seen a picture of it, I do know it.
Yeah, you guys made up my mind. One of my friends mentioned to me it was in Mass Effect too (I barely remember it, but they are right). Anyway, I won't be using it. Adventure 7 (which is what I was asking for) will have a far harder but less time consuming and less well-known puzzle.
How about the square puzzle with 4 groves and a ball in each groove? There is a magnet in the center of the square that attracts the balls as you tip it one way or another. You have to get the balls on the outside of each groove.
