Looking for a Halloween costume idea? Have lots of time and silver spraypaint? Then you can build your own exoskeleton (suck it, regular skeletons!) like Mario Caicedo Langer the creepy starer. Just don't go showing up in these parts expecting candy OR I WILL BURN YOU WITH A CAULDRON OF SCALDING BAT'S BLOOD. You're not purple nurpling me with that robot hand!
