Brian Doom designed and created an awesome version of the Rubik’s Cube that can be played by people with visual impairments or simply folks who want to play in the dark. Instead of sorting six different colours, the “Accessible Cube Puzzle” is played by sorting six very distinct textures:

"A few years ago (2002?) I made this “accessible” cube puzzle by simply gluing/drilling an existing cube. The goal was to get an intuitive sense of “where the cubes went” when a face was turned – by holding the back and viewing the front, the cubist can sense all faces at all times. This makes the design ideal for puzzling in the dark (which I did) but also as an enhancement for the visually-impaired without sacrificing usability for the sighted.

Note that if I had used a simple braille solution with the labeller, the result is quite unusable – a single turn and a given braille character is read as a different letter, if it isn’t already sideways. And reading braille backwards on the reverse of a cube… tricky.

Each face has a unique color, shape, and texture, with the each face’s modification material chosen for ease of recognition relative to the other faces.”
