A change from my usual stuff, this video shows you how to build a Penrose Triangle illusion. When viewed in 2D (on a monitor or with one eye covered) your brain tricks you into thinking you're looking at a series of cubes; tracing the horizontal and vertical surfaces you'll see that these cubes are in a formation that is impossible to achieve.
