This has been going around for a few weeks, so I thought I'd add another post about it in the tens that are out there.
The Cat Piano is a smooth, cool animation about cats, Jazz, and some misguided humans. The film was created by The People's Republic of Animation (PRA). You can watch the animation on their site, and also on The Cat Piano's blog, here.
When I saw the film at Annecy, I loved it immediately. Something about Jazz and smoking animals really gets to me. :) I even bought the shirt:
Why yes, I do know the picture is backwards. :)
Anyway, check it out, and look around on PRA's site, too. They have some interesting work.
