Mastermorphix - 4 Clear Color

The QiYi Mastermorphix is a beautifully transparent cube that hints at its inner workings.  The curved design provides optimum hand appeal.

The object of this puzzle is to scramble all of the sides and then return it back to its starting position. This puzzle is extra challenging because as it is scrambled it changes shape, so not only do you have to put all of the colors on the right face, but you also have to bring it back to the original form.
