It's a prety simple plot of the guy and the girl trying to sneak past the robot to escape. The backgrounds were created in lightwave and then "cartoonerized" using the photoshop poster edges filter. The people were done in poser 4 using the cartoon with line display setting. It was all composited together in aftereffects. The sky in the background is simply a photograph of the sky that scrolls by slowly during each shot. Even though most of the elements were done in 3d programs, the overall look has a real 2d feel to it, especially in the panning shots.
