Sony Echochrome PSP

Featuring an elegant black and white art design inspired by the works of M.C. Escher, echochrome is a puzzle game unlike any other. With gameplay based on optical illusions, players must utilize five simple laws of perspective to join walkways, hide dangers, and create new paths to reach the "echos," or shadow guides.

Once you've mastered the five laws, use them to create your own mind-bending levels to play and share with friends using the custom level editor. [Sony]
