Rubik’s Cube for the Blind

This draft of the famous Rubik’s cube is a test of this timeless toy on the Bedüfrnisse blind people adapt and they “feel” the colors to be. 
The idea behind it is to people who do not have to give up their eyesight, give leave by the colors an insight how difficult it is for blind people, because this version of the cube is about to solve it so difficult for the sighted as it is difficult for the blind, to release the classic dice.
