I have a friend who has a Rubik's cube that looks very much like the orginal design that Erno made, with the corners chopped off. It was strange; at first I thought maybe the corners rotated, as well, but then I realized it was just an optical illusion, it's really just a regular ol' 3x3x3.
Here's Erno's design:
Now, imagine the corners cut off even more, so that the edges are somewhat chopped off, too. That's the cube that I saw.
Does anyone know where to find one of these?
