Actually this is a standard technique in computer graphics, normally used
to generate procedural textures. In fact, you can look up a bunch of texts
on computer graphics dealing with generating randomized spatial distributions
with required properties. I posted a simple coordinate mingler to this
list some time ago, I think Chris might have it archived (I use the same
code in my raytracer, and it looks... random. :) )
