This is a video of Russian cube puzzle fanatic Bondarenkoyt modding a standard Rubik’s Cube for use by the blind by adding different textured squares to each side with a plastic extruding 3-D printing gun. He then solves the cube while blindfolded in around 4 minutes and 15 seconds, beating my record for solving any Rubik’s cube not blindfolded by 24 years and counting.

Keep going for the video.
