Tachikoma is my favorite, C&C War Factory, my second. Then P0pe's work. My girlfriend's in love with that robot; as a graphic designer, she loves the C&C critter, too. The architecturally antiseptic work is excellent as well -- it serves not warmth but idealism. "Builds like a surgeon" was a high (and accurate) compliment. All of the entries are gorgeous and ingenious. If I'd known people here did work of this caliber, I doubt I'd have shown my mug!
