So, freakin' awesome. Made by Ryan Brooks, this cosplay suit is "unique in it's ability to transform from a briefcase into the fully detailed and fully functional suit of armour, this endeavor was inspired by the Iron Man 2 movie." The suit itself was contstructed with over 4000 LEGO Technic pieces and hundreds of pieces of hand-crafted armor.
