Felice Varini’s anamorphic paintings seem senseless until they’re viewed from the right perspective — the key is to find the correct viewpoint. (One clue is that it’s always 1.62 meters from the ground, the artist’s own eye level.)

“Varini catches our eye by introducing an anomalous element into our field of vision,” writes Céline Delavaux in The Museum of Illusions. “His paintings are like frameless pictures that give the illusion of a single plane in three-dimensional space. In his hands, painting works like photography: it flattens a space while revealing it.”
