RUIN is amazing animated short film created by the folks at Oddball Animation.
On top of the obvious awesomeness of the final product, you can check out some test renders and making-of tidbits on their project page.
As impressive as it is, RUIN was not made for a client or done for any specific marketing or commercial reasons. It is an internal project, meaning they pretty much did it for themselves. Now this is a personal project.
