PixarTalk has just posted an exclusive still from the upcoming Pixar short Day and Night. See it above. This style of putting 3D images within 2-Dimensional characters looks like it will make for a very unique and cool short film that I cannot wait to see.
PixarTalk has also posted a picture of Teddy Newton, the director of this short, taken by Pixar's "photographer extraordinaire" Debby Coleman.
See this short starting on June 18 before every showing of Toy Story 3.
