The Rubik’s Cube is an iconic 1970′s 3D puzzle with the ultimate goal, via twisting and turning, of organizing the squares into six solid color sides. But how would you solve that puzzle if you couldn’t see the colors? The Braille Rubik’s Cube designed by Konstantin Datz seeks to answer that question with striking results. The braille word is used for each color so the hues are felt and the puzzle can be solved.
