Dark Vessel is a wonderfully weird animation brought to you by Rocky Curby, a Disney animator. The short takes place in some mismash Western and Sci-Fi setting. I'm only assuming it's Western because of all of the orange and one of the robots is referenced as a Native American. Oh yeah, all of the characters are robots. That's pretty important.
As one gruff voiced robot kills another robot, he eventually has to pay the price for his actions in an awesome way. Dark Vessel is extremely stylistic, wonderfully animated, and definitely worth your time. Just get used to the gruff voice.
