Optical illusions have long fascinated scientists, artists, and everyday viewers. These visual puzzles can make stationary ...

Penrose Stairs is an optical illusion. It is a two-dimensional depiction of a structure representing a flight of steps, but, as Lionel and Roger Penrose described “the connexions ...

Optical illusions are fascinating visual phenomena that trick the brain into perceiving something different from reality.

This tricky visual illusion is also known as a Penrose stair, named after its discoverers, Lionel and Roger Penrose.

Molecular visual illusion: Aromatic ring system reminiscent of M.C. Escher's Penrose stairs (PhysOrg.com) -- Who hasn't seen M.C. Escher's famous picture of the stairs that appear to always go up ...

Similar to M.C. Escher's "Ascending and Descending" and the Penrose stairs, which are both two-dimensional renderings, the illusion by Kokichi Sugihara invites the viewer to first interpret the 3D ...

(Medical Xpress) -- Our interpretation of the world around us may have more in common with the impossible staircase illusion than it does the real world, according to research published today in ...

Ulrich Schwanitz claims to have created a 3-D Penrose triangle without resorting to the usual optical illusions. We'll believe it when we see it.
