Echochrome will be a downloadable game on the PlayStation Store and will be available for the PlayStation Portable. Announced at E3 2007 and created by Sony's Japan Studios, it is a graphically simple puzzle game, with gameplay involving rotating a world occupied by Oscar Reutersvärd's impossible constructions to be traversed by a mannequin figure. 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.
