I would think that there is nothing that would prevent one from doing such a script although I think that would involve some sort of circlepacking algorithm which i assume is fairly a complex matter.

My spontaneous reaction is that it is simpler to do it manually. But maybe there is someone here that is more at home with that sort of math who could do it.
Jonathan (Tile Tool, Roads, Voronoi Tool, Triangular) maybe, from what I understand the guy is VERY good!

Thank you Håkan! Ive been looking for a smart way to do a color-blind pattern, and it seems like I have to keep looking…
/O

Another way to do it is to make a script that, upon drawing triangles inside a shape, also drew the incircles of each triangle. This is not so hard to do but the result isn't very good. There would be alot more space around the circles...

if you send me a more detailed description of how you want the tool to work i will be happy to put a script together

Would love to see this, too!

It looks like this site has a plugin that "resolves conflicts between overlapping symbols," but for some reason, it looks like it's only compatible with Windows?...

Looks like this is a nice solution: http://forums.adobe.com/thread/732621

Would be great if we could substitute the circles for other user-defined symbols, or if we could set circle size instead of relying on a percentage range, but this is really great.
