What's a manifold, James, and how does it contain or describe the subset
of nxn pixels?

I use it in two ways, both kind of mundane -- the randomness isn't really the point,
just an ingredient.
1. I see a huge space of possibilities, e.g. all images of NxN pixels, or all MIDI pieces
of 64 beats or less, and a tiny proportion of them are "well-formed" or
"coherent" according to some artistic sense. In my mind's eye that
proportion is a low-dimensional manifold inside the huge space. Within that manifold I
might not mind which one I get, really, or maybe I just want to get one after another
until I decide to stop. But the hard work is defining a method capable of random sampling
from that manifold. Defining such a method is "metacreation", as in Mitchell
Whitelaw's great phrase, now used in the Musical Metacreation conference.
2. Sometimes I'm using a metaheuristic optimisation algorithm (e.g. a genetic
algorithm), whether interactive or non-interactive, and in that case the mechanisms of the
algorithm have to be randomised, because otherwise they privilege some part of the search
space without justification, so performance of the algorithm is worse than it could be.
