Ok. You've got to watch this one--and watch it full screen. maybe several times. you'll find more and more amazing detail. Here's the wikipedia description:
Logorama is a 17-minute animated film written and directed by H5/ François Alaux, Hervé de Crécy and Ludovic Houplain, and produced by Autour de Minuit. The film depicts events in a stylized Los Angeles, and is told entirely through the use of more than 2,500 contemporary and historical logos and mascots. The film won the Prix Kodak at the 2009 Cannes Film Festival and the Academy Award for Best Animated Short Film at the 82nd Academy Awards.
If Crawford could show this at school he'd probably include it as a resource in his "city of dreams" project and have his students view it when they read "In Persuasion Nation," a short story by George Saunders.
warning: contains tarantino-like dialogue. language that would make crawford's mother cry.
