For the upcoming "Paint Wars" scenario game in Novemeber at 24HourGames.com, it'll be great for the Empire side. With a little painted cardboard and duct tape mod it could be Vader's helmet (or Dark Helmet from Space Balls), paint it white and you have a Stormtrooper helmet. BTW, nice one Sam!
It really looks like a heat trap, especially in the summer and early fall months. Maybe adding some heat vents in the top of the helmet would help out.
