For the record, povray is a nonfree (but free-as-in-beer) raytracer.
Is there any site policy about art generated by such tools? Is it free enough for OGA?
More specifically, I wonder about GPL'ed 2D art, where the source is povray code.

All the art I posted so far is made with POV-Ray, and nobody seemed to mind. Also, POV-Ray isn't exactly closed-source either, so I wouldn't worry.
Yes, POV-Ray art is just fine. You may include the source code if you like, but that's not necessary.
