Minifig Generator ; from Baseplate. This neat site lets you arrange different body parts on the little, Lego (r) people. Or, let it make completely random folks.
Start with this screen:
After you've made your creation, click on the "build" button on the right, and your Minifig (c) will appear in a new window. For legal reasons, you can view your figure, but cannot download it. Still, much fun.
