Patterned Paint

 Pigments which forms Turing Structures

Instead of using pigments which are fixed with one single color, using pigments which chemically react with each other, in such a way as to create spots or stripes, similar to the reactions which create the patterns on spotted or stripped animals.

       Before boning this, check his link. It seems like it's possible.

       Is this a loop chemical reaction? How long will it run for? Is it like the monkey/type writer thing and eventuarly you end up with the Mona Lisa?

       Yes! Hodgepodge paint. Brilliant.   

       I think the trickiest part would be getting the pattern to fix in as the paint set.
It might be handy to have the initial reactants in two separate pots, mixed at the time of application.

       You would definitely need to have the initial reactants in two seperate containers, since one generally needs at least three chemicals reacting with each other to produce turing structures, and at least one of them gets "used up" as the reactions continue.   

       As for getting the pattern to become fixed as the paint set... that could simply be a matter of adding something to the paint to make it dry extra slowly.

       This is quite baked in many old cartoons, particularly Buggs Bunny and Tweety & Sylvester. They never bothered to explain the chemical make-up, but paint with patterns was exhibited many times.   

       Also, upon Googling your title, I found many hits for patterned paint. See links. I'm not sure exactly what patterns are available, but there are quite a lot. I'd say your idea is awfully close to being Baked, if not quite cooked all the way through.

       I don't consider those roller-based paints as equivalent to goldbb's idea.
There is something more similar in existance, called Hammerite. Which is lovely stuff. It's for protecting rusting metal really, but the cool thing is that it <presumably> uses the cell convection pattern of the drying paint to set up a 'hammered metal finish'.		   

       goldbb, my concern with the pattern 'fixing' is really about it not just drying to a uniform colour. A requirement might be that the reaction proceed for a period then stop relatively quickly. That is, if the reaction slows down gradually the pattern may be lost. You don't want the reactant to get used up before the paint has dried.
I wonder whether it would be possible to use solvent evaporation to power the cycle. That way maybe it wouldn't matter.
