I do not use a computer but I found it useful in keeping track of

moves and testing various transformations. I can fix the cube

now in 5 minutes or less. In fact, I have won cubes at

stores by challenging the owner to a

freeby if I can do it under 10 or 15 minutes. My transformations are

very easy to remember because after one face is complete I need only 4

to fix the cube. The transformations are positioning the corners, toppling

them, fixing edges and then toppling edges. These are not designed for

speed but for simplicity. I have taught some people to solve the cube this

way with a few hours of practice. To do it in 5 minutes, however, requires

a few more transformations.
