I guess the standard size of computer keyboard keys fit the rubik’s cube perfectly, you can easily convert your own rubik’s cube into a keyboard by glueing the keys on them. Of course, you might want to spell out some words you want “matched”, that’d be more fun than simply matching colors.
Tired of the normal Rubik’s cube challenge? Have the keyboards from a dead computer? Well, here is the thing for you! The Keyboard/Sudoku Rubik’s cube!
i got the idea when i popped off a key from my key board and looked at its shape, and it fit perfectly on my Rubik’s cube
