This is a simple test of physics on BGE (Blender Game Engine), recorded and used as a scene animation.
Rendering is made with Blender Cycles, unbiased render engine developped as a Blender Project. wiki.blender.org/index.php/Dev:2.5/Source/Render/Cycles
I know, the "slow" part is not really "slow" compared to the first animation... I realized afterward that I have badly setup my animation exports...
