Salesman Pete and The Amazing Stone From Outer Space. If you have to watch a video during lunch at the office, this is it. It's pure animation bliss, with the most exquisite use of 3D I've ever seen.
The atmosphere, the pace, the action... and also the perfect rendering to make it look like pure airbrushed, hand-drawn 2D animation. Marc Bouyer, Max Loubaresse, and Anthony Vivien—as well as musician Cyrille Marchesseau and sound designer Mael Vignaux—should all get an Oscar and jobs at Pixar. [Salesmanbuck—Thanks Woltz!]
