The results of an afternoon messing around in Blender.
Seriously, nothing too terribly exciting.
Motion: a subdivided plane with cubes parented to each vertex. Wave modifier applied to the plane and animated over time.
Camera (for this short): sideview-ortho perspective.
Material: simple white diffuse (no spec) with ray-trace mirror (very low). Colored by an animated line of spot lights, and Ambient Occlusion.
