Do you want to watch anime so artsy that will either relate to the deepest part of your soul or completely confuse you?
Well here you go, and since they are so short you don't have to feel like you wasted your time.

This list includes arthouse anime that are around 15 minutes or less, so movie length (Angel's Egg) or OVA/episode length (Cat Soup) are not in here.

Some of this may be a bit challenging to find, some are up on youtube and for some you'll have to get creative, buying or streaming them is probably out of the question.

This is a compilation of Avante-Garde shorts that are unique, mind-blowing and addicting. These will give you a different POV on the world of animation.
Includes short films, short series, commercials, station IDs, and specials.

Worst rated anime according to MAL

Welcome to the black hole of anime.
The weirdest, most unsettling, gory, nonsensical stuff I somehow managed to enjoy.
