Pixie, The Renderman alternative

Straight out of one of the top ten CS departments in the nation, U.C. Berkeley:

Pixie is a RenderMan like photorealistic renderer. It is being developed in the hope that it will be useful for graphics research and for people who can not afford a commercial renderer. Pixie is an open source project licensed under Gnu Public License

Nice part about this? It’s like what Pixar uses. Written for Linux, and Windows. Sexy.
