Born by Myself

Before experimental shorts were referred to as "Avant Garde" MAL called this genre "dementia", named after the mental disorder, but because these anime are generally poorly animated and have no story, characters, or substance I like to call them "demenshits". This is a selection of these types of anime if you feel inclined enough to become enlightened to the world of demenshits. Some of these may feature flashing lights and/or obscene imagery so watch at your own risk.

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.

These are anime Iv seen that I feel have an undercurrent of sadness to them. Hopefully you find something new!

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

Guaranteed to make you say "what the fuck" or get your money back.

These stacks are meant for cataloguing every stop-motion animation on Myanimelist. The list is the result of research by the Stop-Motion Animation Appreciation Society:

Stop-motion is a form of animation in which objects are manipulated little by little while each frame is shot separately. Puppet animation is the most common, but before 1935 cutout animation was also very common. Among other types are claymation, pixilation (now removed from the database), object and model animation. In this list also works using sand, charcoal or paint are included, since in the form they've been accepted to MAL, they also include gradual manipulation and shot by shot filming.
