Echochrome

Echochrome is a 2008 puzzle video game developed by Will and Japan Studio and published by Sony Computer Entertainment for the PlayStation Portable (PSP). A PlayStation 3 version was released the same year in North America and Europe. The gameplay involves a mannequin figure traversing a rotatable world where physics and reality depend on perspective. The world is occupied by Oscar Reutersvärd's impossible constructions. This concept is inspired by M. C. Escher's artwork, such as "Relativity". The game is based on the Object Locative Environment Coordinate System developed by Jun Fujiki—an engine that determines what is occurring based on the camera's perspective.
