It didn't take much work at all - mainly deciding which cube moves transfered well. The only really diferent moves involved switching edges on the last face, or flipping them. Both had fairly easy solutions. I do one face first, and then work upwards from there. There is a 7 move sequence on the cube, which moves an edge from the upper face to a middle edge, which transfers nicely to the Megaminx.
Corners just work, without any special algorithms.
The 4 move commutator F R' F' R moves to the Megaminx and will move corners around. Of course, none of the slice moves work, so new edge moves are needed. We also need an easy way to move centers, and to move stars around, to make pretty patterns. By the way, the one two I got, and several a friend got in L.A., all had 10 colors, with red and yellow duplicated. I don't know if the 10 colors are a mistake or intentional.
