I'm filing this under 'pretty damn neat' until the sun explodes.
Boys Who Like Ponies is an animation project completed in three weeks by a Norwegian student detailing the brony subculture. Obviously most of the information is completely old hat to anyone reading this, but the animation is cute, well-done, and rendered in an interesting style that both mimics the show's style but adds a touch of the artist's style that I'm really digging a lot.
You can find the documentary after the break. It is in Norwegian, but there are English subtitles as you can see from the preview.
