Wall art that reshapes reality.
Impossible Corners™ are illusion-based wall installations that make space behave... strangely. As you move, a floating object appears to twist and shift in impossible ways — revealing the hidden mechanics of perception itself.
Blending science and art, these pieces invite a moment of deep, quiet wonder: a felt realization that your mind doesn't just interpret reality — it constructs it.

How is this even possible?
"Impossible Corners uses three peel-and-stick panels-aligned precisely in the corner of a room-to flip your sense of depth. Designed with carefully calculated visual cues, the decals trick the brain into seeing the corner as protruding outward, not receding.
This illusion works because your mind trusts the perspective cues it sees. Even when you know how it's done, the effect remains strangely convincing-especially as you move. Thanks to a principle called Gestalt closure, your brain fills in missing information to create a seamless, but entirely false, reality.
Your perception can hold the ordinary room—or the illusion—but not both at once."

FAQs
What is Impossible Corners?
Impossible Corners are a series of three designs by Jeff Lieberman, that when placed in the corner of your room create the illusion of geometric shapes that move and shift with you as you move around the space. Each 'Impossible Corner' is made of three precisely designed sections: two wall pieces and one ceiling piece - that when combined, invert your perception of space.
How do I mount it?
Follow our installation video for easy instructions on how to mount your design. Preparing your walls ahead of installation is the key to keeping your Impossible Corner as sticky as possible.
Will it damage my wall?
No! Impossible Corners are designed to be removable and reposionable throughout their lifetime. They use a special adhesive that will not cure to your walls or cause any damage.
