There exists a commercial system which simulates the effect of charcoal, oil pastels, oil paints and graphite pencils, on various (rough-textured paper, muslin, etc.) backgrounds. Its name eludes me, but I can find out more info if you're interested. (It was advertised in Computer Graphics World last year.) The results are quite good, with apparent "shadowing" from paint blobs, etc. There's also last year's SIGGRAPH paper on "impressionistic" painting systems, for which an (undocumented!) public-domain SGI executable exists. Although its physically-based modeling is minimal, it can do a superb job of mimicking the results of "traditional" painting. Another recent paper in this area (auto-producing "paintings" from images) exists, specializing in simulating oils (?). Either in the Visual Computer or IEEE CG & Applications, I think (last 6 months). For any given medium, there is a huge range of effective ways to paint/draw. Just thinking about watercolor, for instance, all the variables... the dampness/dispersion qualities of the paper, how quickly the paper dries, the amount any given area has been "worked", the pigment/water ratio in the brush, the zillion ways in which the brush is used to blend/apply pigment, etc. It's a challenge..
