I think a picture is worth a 1000 words, and a video is worth 10,000.  Here
is the link to implicit canvas youtube video and paper so you guys can see
what it's all about.

paper:  http://zurich.disneyresearch.com/OverCoat/

Looks exciting to me, not sure how much I would personally use the NPR
stuff though.  I've not read the paper so I don't know if there are deeper
implications though.
