Exhausting the entire problem space of animated teddy-bears, cars, people and pigeons

Animator/composer Cyriak just posted this surreal video featuring infinite giant teddy bears climbing out of the sea at the Worthing shore and crossing the road. You'd think that this would be thin gruel for three minutes' worth of animation, but you'd be wrong: it turns out that the number of variations on the themes of pigeons, people, teddies, cars and shore is a lot greater (and weirder and funnier) than instinct would suggest.
