A Linux Rubik’s Cube
Recently some friends were spending most of their time in solving the Rubik’s Cube (3×3x3), finding new fascinating algorithms and reducing their time to the minimum. I think their record now is about a minute and a half, maybe less. But as professional geeks they decided to take it one step further.
The solving is now more difficult, as the image in the middle can be in wrong rotation, a problem which can not be seen in monochrome cubes.
