Bloodfeathers is a a creepy claymation short animated by Vanessa Soberanis with sound design by Ryan Edberg. The story centres around a robot who "longs for the impossible", which ultimately causes it to descend into disturbing fits of rage and, ultimately, self-destructive madness.
The animation style and character designs are weird and gorgeous, and the subtle but unsettling soundtrack / voice acting fits it perfectly. The film is only around eight and half minutes long, so obviously there isn't a huge amount of character development, but there is more than enough content and the ending provides a satisfying - and somewhat inevitable - conclusion. If you enjoy animated work by The Quay Brothers, Jan Svankmajer, or the stop-motion music videos of the band Tool, you'll probably enjoy Bloodfeathers too.
