I first read about the Rubik’s Cube for the blind on Yanko Design a while ago: ‘This current iteration uses only Braille. Colors embossed include green, blue, red, yellow, white & pink. One of the more sensible concepts in a long time that hopefully will delight the sighted folks too!’
Last month, Maria Popova (whom I’m following on Twitter @brainpicker and you definitely should as well) posted about this Rubik’s Cube. She also added a link to one of her always interesting posts published on Brain Pickings: Talk to Me: Design and the Communication Between People and Objects.
This Rubik’s Cube was designed by Konstantin Datz.
