Granted, you have presented some good points for your case. However, I'm still at odds with what I see as a baseless assumption that the burden of proof lies on one side more than the other.
Anyway, has anyone seen either of the Blender open movie projects? They're both available for free from the Blender Foundation under Creative Commons licenses. I downloaded them the other day and I'm glad I did, because they're fantastic.
The first is "
Elephants Dream", which is a mind-bending short about two men exploring what appears to be a mechanical dream world. Personally, I'm really into what I call "imagination flicks", the kind that transport the viewer into another world, immersive and alien. Examples include
"What Dreams May Come",
"Gwai Wik" aka "Re-cycle" (my favorite movie of all time), and to a lesser extent "The Cell". If this animated short were made into a feature-length film, it would surely be one of my favorites. As it is, it's a great way to spend about 10 minutes of your life, and also a pretty impressive testament to what Blender can do.
The second is "
Big Buck Bunny", which is a comedic short about woodland creatures invading the title character's territory, and his revenge. I'm not normally a huge cartoon fan, but this film is one of the funniest I've seen in a long time. There's no dialogue, but believe me that it doesn't need it. The animation quality is the same as you would expect from high-end motion picture studios like Pixar and Dreamworks from a few years ago (e.g. "Monsters, Inc."), and really solidifies Blender as an industry-quality animation program. If you liked the squirrel scenes in the "Ice Age" movies, then "Big Buck Bunny" is right up your alley. It's also fun for the whole family.
