Optical Wonderful
Notable Illusionists & Artists
Every illusion has an origin story. These are the mathematicians, psychologists, and artists whose names are attached to the tricks in the library.
Akiyoshi Kitaoka
The Japanese psychologist behind Rotating Snakes and dozens of other peripheral-drift illusions that use color and contrast alone to create the sensation of motion in a completely static image.
Op art, geometric motion illusions in fine artBridget Riley
The British painter whose precisely engineered black-and-white and color compositions helped define Op Art in the 1960s, using repeating geometric pattern alone to produce sensations of vibration, flicker, and movement on a static canvas.
Large-scale anamorphic installation artFelice Varini
The Swiss-born, Paris-based artist known for painting geometric shapes across entire buildings, streets, and landscapes that only resolve into a coherent form from one precise viewing point.
Pavement/chalk anamorphic artJulian Beever
The English chalk artist who popularized photographable 3D pavement drawings - anamorphic street art that appears to leap off the ground, but only when viewed from one specific camera angle.
Impossible architecture, tessellationsM.C. Escher
The Dutch graphic artist whose lithographs of impossible staircases, endless waterfalls, and interlocking tessellations turned mathematical paradox into some of the most recognizable images in art.
Early impossible-object drawings, precursor to PenroseOscar Reutersvärd
The Swedish artist who drew the first known version of the impossible triangle in 1934, decades before it was independently rediscovered and formalized by the Penroses.
Penrose triangle and stairs (mathematical formalization)Roger and Lionel Penrose
The father-and-son pair - a psychiatrist and a mathematical physicist - who formally introduced the impossible triangle and impossible staircase to the scientific literature in 1958.
Surrealist double-image paintingsSalvador Dalí
The Spanish surrealist whose 'paranoiac-critical method' produced paintings built around deliberate double images, hidden figures, and visual puns that reward - and reward again - a second look.
