How to draw a Penrose Rectangle & other impossible objects

The Penrose Rectangle is what’s known as an impossible object, an optical illusion that is drawn to look like a three-dimensional thing that could never actually exist. If it’s hard to see at first, cover one half, then the other, and then look at it again: it’s a geometrically impossible shape.

Jonathan Harris draws objects in YouTube videos (including possible ones), but he has a series of impossible objects that are fascinating to watch and learn, including the Penrose Triangle, an Impossible Oval, and the Penrose Staircase:


We love these impossible forms, as proven by our logo. And if you draw any impossible objects, tweet us a photo of it. We’d love to see!

There are more optical illusion videos in the archives, including the not-to-be-missed work of Kokichi Sugihara, who builds impossible drawings in three dimensions.

This Webby award-winning video collection exists to help teachers, librarians, and families spark kid wonder and curiosity. TKSST features smarter, more meaningful content than what's usually served up by YouTube's algorithms, and amplifies the creators who make that content.
