Rubik's Cube Simulator
This is a project I was very interesed in starting during my trip to India over the summer of 2014. At the time I did not know much about how to do this, but someday if I find the time I will come back and work on this.
UPDATE: I decided to make a Rubik's Cube simulator in three.js. You can find it over at my CubeSimulator repo.
