iPhone Rubik Cube Solver

A new iPhone app called CubeCheater helps you solve the classic Rubik’s Cube puzzle toy using a mix of sophisticated algorithms and simple image-recognition technology.

You take six pictures of your mixed up Rubik’s Cube using the iPhone’s camera — one photo per side.
CubeCheater is able to recognize the placement of each colored square and generate a map of your cube. It then figures out the quickest path to solving the puzzle and gives you a set of easy-to-follow, step-by-step instructions.

CubeCheater even works in reverse — create a virtual mixed up cube inside the app, and it will tell you how to twist a solved cube to match your creation.
The application sells for $1 in the App Store.
