Nick Cross (Over the Garden Wall, many other cartoons) just released a 3 and a half minute movie called The Clockwork Elves. It's absolutely stunning. It's free to watch on YouTube.
CW - it contains gore and disturbing images.
The Clockwork Elves could be a pyschotropic exploration of spirituality and death - or it could be a tale of a little goofball hopped up on goofballs. Either way - it's a cartoon.
