non photorealistic rendering

 From:  DannyT (DANTAS)
I'm very interesed in cartoon type rendering, I've done a pretty extensive search on the net, no luck.
Would anyone know of any non photorealistic rendering software, like Penguin for Rhino.
Preferably standalone, or a technique with the popular rendering apps would be ok.
I don't want to resort to installing a modelling app just for the render plugin.

Thanks in advance
