The Blender Foundation is getting ready for Siggraph 2013 and they are compiling a new Blender Reel (here's the one from last year). Mike Pan is calling all Blender Artists to contribute their work, and help promote Blender.

The work you submit here will be considered for the Blender 2013 Demo Reel to be displayed at Siggraph and online.
We accept finished animations, break-downs, and still images made entirely, or with the help of Blender.
