Andrei Dragus told me this problem on a road trip a year or two ago.
M marbles are placed in N cups arranged in a circle. One move consists in choosing a cup, taking all the marbles within that cup and placing them one by one in the following cups in clockwise order (since the cups are in a circle you might end up putting marbles in the original cup as well).
