A video by Michael Levy done in Maya to the music of John Coltrane. Flawless timing and a brilliant idea.

A well animated, moving video by Yannick Puig. He created it to illustrate the great music of Kwoon. Nearly brought me to tears the first time I watched it.
The geek in me really likes the mix of 2D and 3D elements, and the great depth of focus used.
