I found a method for the 2x3x3 with a ring in it ("Crazy domino"?) on my way home. Any one else, who want to trade methods and algs?
I haven't spent much time on the puzzle, so I don't really have a complete method, but my approach is to leave the centers last. I don't have many pure center algs but (M' U2 M U2)3 is probably the most useful one I'm aware of (actually Johannes came up with that one during our trip). The other algs I know are something stupid like first doing H-perm (the MU-alg, doesn't affect centers which is nice) and then solve it with (R2 U2)3 (F2 U2)3. Also you can do T-perm and solve it mirrored and it affects some centers.
Rob and I spent our whole journey home figuring out what on earth was going on, and then found some algs for it. We might create a thread on it sometime. Basically we did domino solve and then really silly long algs for centres (like sexy x 15). The crazy thing is that the alg's effect varies depending on which side you do it on, so we figured some of that too
EDIT: Btw, does anyone have the FMC scramble? I have my solution, but no scramble (yes I know I can do it backwards, but I'd rather have the real thing!)
