We are already making open content projects since 2005 (tutorials, movies and a game). In that period we've modeled, textured, groomed and rigged dozens of great characters!
In the coming period we will update and refresh our characters, make them available here as simple download, fully rigged and render-ready in the last version of Blender. All characters are available under the permissive CC-BY license (use as you wish, just give a fair credit).
Coming soon: Victor, Emo and Proog in full Cycles glory, and the Quadbot.
