Raketentim sez, "The Halo Corpse Alphabet is a rather macabre project with the goal being to represent every letter of the alphabet by the twisted, curved, stretched, and otherwise dead Spartan and Elite bodies from Halo 3. The Halo community was clearly up for the challenge as they miraculously managed to capture every single letter, number, and even some punctuation in the form of screenshots."
(Thanks, Raketentim!)
