I wrote a tool that can be used to generate "body paints", or those clothes that don't use any special mesh, but are just an alpha and a texture, glued over the body.
I posted the tool in the adult site, because it's trivial to use it to create adult clothes. But maybe I could post it here - unless there's some objection.
Today (2006-10-22) the tool can generate two types of bottom (a bikini-like and a gym-shorts-like), three types of top (a sleeveless shirt, a soutien-like top and a "tomara-que-caia"-like top (this is the Portuguese name, meaning "I-hope-it-falls"; it's a cylindrical top like a belt), and paint stars all over the body.
I placed it in the adult site because there's no restriction in the tool to suppress parts of the clothing, to make it transparent, to make it "miss" some critical places of the underlying body - but anyone with experience with BodyShop can do it too.
The tool runs in the R-language, a programming language and environment fitted to statistical analysis and graphics. But it's free (meaning free beer and free speech) and available for most OSes, and it's quite simple to use:

Let me hear if I can post it here without the risk of being banned :-)
