Brian Doom, that is. And since the website of Doom doesn’t include any information to the contrary, I’m going to go ahead and assume Brian must be a doctor of something or other. For obvious reasons.

Anyway, Dr. Doom saw this morning’s Rubik’s cube for the blind post and did one of my very favoritest things for a reader to do: He one-upped me. Best of all, he one-upped me with his own work. This modded cube he made is not as randomly kit-bashed as it might look. When solved, each face features a unique color, shape, and texture, making it equally useful to both sighted and sightless solvers. Doom himself explains:

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.

[Thanks, Brian!]
