Friend of mine two Halloweens ago dressed up as Tony Stark after Ironman came out. He was one year behind me at Clarkson, graduated as a Mechanical Engineer, now working on his Masters (possible PHD), and is the most adept person I have ever know when it comes to machining and design. He created his own Arc Reactor for this costume (all be it without the same awsome high wattage) and certainly has the look to play the part. As far as I'm concerned, he IS Ironman.
