Rubik's cubes are awful, frustrating objects. Sure, if you like a challenge I'm sure there's some fun to be had there, but to me, they're just pure pain. And this Rubik's cube for the blind? Forget it.
But this wasn't made for me, it was made for the visually impaired. And if they really want to enter this world of pain and frustration, that's their prerogative. Just don't say I didn't warn you.
