I actually don't mind the idea of a spray-paint macro - other than the 
shear number of objects involved - it seems as though it would provide 
an ideal way to apply certain textures, like stencilled lettering. 
Where a texture overlay might wrap around objects, the spray-paint 
method would not, it would only cover front surfaces.

I've been thinking that, if I limit the sprayer to a single color, and 
union all the particles to be textured as a set, it would be more efficient.

I also have ideas for allowing the use of a spline as a pattern, rather 
than an image, but I'd like to get it working for images first (black 
and white only, for now)

suggestions are welcome.
