Of all websites that provide explanation about how to solve the cube, I found that Beginner's Rubik's Cube Solution is the best. The website provides java-based cube animations to demonstrate how the algorithms work and enable you to develop your own best rhythm. I like it.

Shape changes to the degree which it turns. When you are done it becomes a cube

I was dumbfounded after perform several twist to scramble this cube. It's amazing. You hardly notice which part is the right one for each position. The same color in every face adding the confusion. It feels like the cube changes its size. It looks like a Transformer robot in transformation phase, not a robot yet but not a car either. It took me quite sometime to understand the principle of the mirror cube. But definitely, no speeding using this one. Really love this one.

Oh, don't forget that it's round. It's got to be another Rubik's to pursue, though I'm not sure it's the right time. Anyway, it's Rubik's 360. Test it by follow this address.
