This is the Rubik’s Tactile Cube, a Rubik’s Cube with sides that are identifiable both by their color and tactile pattern (currently on sale on Amazon for $11). Not only are they perfect for the vision impaired, they’re also great for anyone looking to increase the challenge of cube-solving by completing the puzzle blindfolded or in the dark, which, coincidentally, are also two of my favorite ways to make love besides pretending we’re both wearing jetpacks.
