Ha! I came across an article about 25 of the most creative videos on YouTube, wound up at http://www.youtube.com/play, then over to the shortlist.
One of the videos there was a delightful animation "The Aborted Earth: The Quest Begins." (Click image below for the video.)
From the description:
'This Aborted Earth' immerses the viewer in a surreal retro-Gilliam world composed entirely of animated black and white engravings from the 19th & early 20th century. The result: an incredible misfit earth skewed violently from, yet oddly related to, our own reality. The Renaissance, the Enlightenment, the Industrial Revolution: all failures. Chaos, desolation and destruction abound. And so, from a tyrannical church-state, one of the only remaining bastions of "civilization," a sacred quest goes forth. A holy - albeit bloodthirsty - knight, General Thaddeus Twer, must seek the last good man on this ruined world (for reasons murky at best.) Accompanying him: Saint Gluestick, a sarcastic skinless horse, unwillingly canonized and drafted for the mission.
Another amusing video by the same creator is This Aborted Earth: Webisode 1 - "Ah... Corpses!"
These are a "must see!" Enjoy!
