Well, it seems Tim's method produces a very similar result to mine, with maybe
just a little more clumping. It does take a lot longer to parse, however -
although it's difficult to compare exactly because he sets a max loop counter,
not a max hit counter, and mine just takes a grid spacing.

I am going to fiddle a little more with mine, then I'll post the source.
