Western Spaghetti is a new (and utterly adorable) stop-motion film made by the fine folks at PES. Rubix cubes, tin foil, rubber bands, post-it notes and candy corns all go into making this delicious meal/movie.
Also check out their other films, most of which also employ household objects and toys. My faves are Game Over (where cupcakes are used in old-school arcade games like Space Invaders, Frogger and Pac-Man), Moth (where a tape dispenser is a frog that eats bulldog-clip moths), and KaBoom! (where war is a mixture of toys, popcorn and circuit boards).
Also be sure to watch the "Making of KaBoom!" video.
