Iron Man - Tony Stark

Do you know how amazing it would be if you were Tony Stark?  Pretty darn.  Lot's of money, genius level intelligence, dashing good looks and a nifty flying suit.

Granted, this Tony Stark isn't particularly dashing, and he probably does not have boatloads of money, but what he does have is an amazing, subtle cosplay.  I really want to know how he got his chest to glow.
