I think it is a fundamentally different thing. Of course you can take
a scrambled cube and interpret some meaning into it (e.g. the four
corner orientations in the L layer look like "the wheel") but so can
the chess masters for random chess boards (e.g. those three pieces are
lined up as "pin").
A chess game always starts with the same state (unless we're talking
about Fischer's random chess) and goes on from that in meaningful
ways. A cube on the other hand starts scrambled, i.e. is meaningless
right from the start, and only becomes "more meaningful" the closer
you get to the solved state.

Ok... um... damn... I'm not good at joking when I'm expected to. I
also can't tell jokes.

An important aspect is that we're looking for *exact* memorization.
You can't make a single mistake or else you'll get DNF. Also, the
memorized object should be "random" and have many different possible
states.
I can't think of any right now, either. Anyone?
