Don Hertzfeldt’s “Genre” is a very comical short that will inform you about various genres of the art world and teaches us what happens when we give everything a label. Check it out because it is very well done, I LOL’d at 0:52 AM, while I rarely LOL at all. Very well structured and executed, with patience that I have respect for.
You may also already know Don of his other work, like Rejected Cartoons. Check out his Wikipedia page. Even his works have their own wiki’s, respect that! :P There’s also his Bitter Films website but to be frank it’s a pain to the eye and a little boring.
