here is a scene I made, I am sure others can do better,
but can a game level be art in motion? like a non static animation?
like a “Art in motion” thread?

Thats actually a pretty great idea.
As a forum section itself would be great, but the idea of being able to showcase someones art in a different way rather than 2D images and movies.
A sort of 3D gallery to showcase ones work would be a superb idea and very creative.
Just add a avatar to the BGUI end 
We have a bunch of work making something 3D and then we output it to a picture 
…It would be allot more cool displaying the models in a way we could rotate/move them interactively or even play an animation wile doing it so.
The only reason we don’t see allot of this stuff already I guess is pretty much just hardware and Internet limitations.
Here it is one place that I know:
