Cat Piano...A Shangri la of Awesomeness

Cat Piano is an awesome short animated film. It was voted one of the top 10 shorts of 2009. A well deserved honor. Definitely entertaining to hear and beautiful to watch. It feels like a very hip Christopher Walken is reading a poem to you...about cats. However, it's more awesome because you get Nick Cave, the Australian singer, narrating a film noir tale about cats. Also, you can find the poem here and watch the short film below.

2 Batman Shorts

These are live-action shorts made of Batman. Both deal with the metal illness aspect of Batman/Gotham pretty well. However, one is more visually appealing.

Ashes to Ashes

This is the more visually appealing one. I should note that it is NSFW and French. Here is what their site has to say about it

Ashes to Ashes is an unofficial short film shot in 13 days and postproduced in France between 2006 and 2008. This fan film is based on the Batman character created by Bob Kane and on the graphical universe of Franck Miller’s Sin City. Original screenplay by Samuel Bodin and directed by Julien Mokrani & Samuel Bodin.

City of Scars
I can't find as much information on it.

When the Joker escapes from Arkham and murders the parents of a young boy, Batman recalls the pain of losing his own parents as a child. He is pushed past his limits to the point where his focus becomes revenge on all who stand in his way, including many of Gotham’s underworld. Finally, Batman is forced to look at the psychological profile of his own mind and except the consequences of his life to find resolve.

Written and directed by Aaron Schoenke, the short was filmed with High Definition cameras over 21 days with a budget of only $27,000.
