"Attractors"

When surfing the Web looking for new and interesting pigment patterns that I
could implement, I came across some very cool looking stuff.

The idea is that a pattern is somehow modulated by its proximity to points or
even lines.  Any attribute can be modified - size, shape, color, position, some
other more complicated thing like a parameter of the underlying pattern, etc.

I've experimented a little with this in the past, but didn't know that it was a
fully-developed "thing".

Here's a sinc function that modulates the size of 3 different object grids.
