FAQs
How is this even possible?
How is this even possible?
The illusion is deceptively simple — and even once you know how it works, it can still feel unbelievable. Three peel-and-stick panels (repositionable, paint-safe) are precisely aligned along the walls that meet in the upper corner of a room. Each decal is designed with carefully calculated visual cues that reinforce the illusion of an inverted space — making the corner appear to protrude outward instead of recede, flipping your sense of depth and reality.
This works because of the mathematics of perspective — when the decals generate the same visual input as if a floating object were present, the mind has no reason to reject that interpretation. Surprisingly, the illusion remains convincing even as you move —reinforcing its legitimacy and causing the brain to lock even more deeply into the perception of a rotating object suspended in the corner. Thanks to an effect known as Gestalt closure, your brain connects visual clues into a single, coherent image — even if that image isn't actually 'there.' With Impossible Corners, the mind can either maintain the ordinary perception of the room, or it can flip into the illusion — but it can't hold both at once. The stronger the visual cues embedded in the graphics, the harder it becomes not to be pulled into the constructed, false reality.
One of the most profound and beautiful aspects of Impossible Corners is how it exposes that perception itself is a construction of the mind. Is seeing the illusion false? Is viewing the room in the "normal" way true?
From a wider view, both are equally real — and equally false. Our entire 3D experience of space is not discovered, but generated.
Impossible Corners points to the underlying informational reality beneath any conception of space and time.
We do not live in reality, we assemble it.
This echoes a core insight of Buddhist thought, where the term emptiness (śūnyatā) refers to the constructed, interdependent nature of all appearances. What is real if I can flip my perception inside out at will? Impossible Corners is a quiet reminder of the mind's power — the power that gives rise to space, time, and everything within them.
What are Impossible Corners?
What are 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.
