Akikan - Carbonated drink cans that are actually girls that fight in a government funded war to decide whether aluminium cans or steel cans are better, it's also like a romcom thing.
School Days - Kinda like a romance, I'll let you figure this one out yourself.
Adventures in beauty wonderland - a 5 minute long acid trip
Utsu Musume Sayuri - About 3 minutes long, it's about a girl? that strikes a thing I guess
Rayca - A bit longer, about half as long as an anime episode. Actually have no idea what happens in this one.
Abunai Sisters - Girls with big boobs protect the booby stone from two people, grotesque art and a plot focused around boobs. In total about 30 minutes long.
Shitcom - A wedding proposal with a twist, and another twist, and another twist. About a minute long or so.
Muybridge no Ito - About 13 minutes long, tells the story of the life of Eadweard Muybridge but it looks really strange and artsy but not really in a good way.
DearS - Alien girls come to earth to become slaves
The Embryo Develops into a Fetus - very short and pointless animation
Some good stuff:
Nazo no Kanojo X - A girl falls asleep, boy licks her drool, a weird romance story begins. Also the girl keeps scissors in her pants or something.
InuHasa - A boy dies, but is reincarnated as a dog, taken in by his favourite writer who is also a sadist and I don't even know what their relationship is tbh, then some other perverts join and whatever.
Stuff I haven't seen but that sounds weird:
Spaze Oz no Bouken - The wizard of Oz in space
Inferno Cop - yes
Basquash - Mecha basketball, on the moon.
