You hold a shape that looks like one thing, then turn it and see something totally different. The ambiguous cylinder illusion lets your eyes play tricks on your brain. This printed toy shows you how a hexagon can look like a square depending on where you stand.

The design comes from Tenrop and works because of how the shape is built. Print it yourself so you can hold it, twist it, and watch the illusion happen in real time. Great for anyone who loves puzzles, optical tricks, or just cool things to build at home.

Use this file to print your own copy and explore how perspective changes what you see. Kids and adults both get amazed when they figure out the trick.
