It’s like one of those optical illusion puzzles where you look at it and you look at it, and you just can’t see what you’re supposed to be able to see, and then all of a sudden bang! You get it! Then you’re not actually SEEING anything different than you were looking at all along, but all of a sudden the perspective is there, and you can see what the puzzle is all about. And once you see it, it becomes easy to see it again whenever you want to look at it.
