Details: This poster has many layers and ideas in it, including optical illusions and elements reminiscent of M.C. Escher. Noticable sponts include the crouching figure in the bottom right, the face on a playing card (Ace) and ink drops melting into a night sky.
An optical illusion is characterized by visually perceived images that, in common sense terms, are deceptive, misleading or somehow trick the eye. There are physiological illusions that occur naturally and cognitive illusions that can be demonstrated by specific visual tricks. M.C. Escher was known for his often mathematically inspired works which feature impossible constructions, explorations of infinity, and tessellations.
