I can't tell you how much I want to play Fallout 3 again after seeing the Fallout 3 replica helmet. This helmet was designed and built by Josh Jay who is an extremely talented and uber-geeky artist.
The Fallout 3 replica helmet is modeled after the in-game helmets worn by the Brotherhood of Steel. If you know nothing about Fallout 3, then the Brotherhood of Steel was a group of good guys who wore badass armor and attempted to restore order to post-apocalyptic America. Now that you're educated you should be able to appreciate Jay's work a little more.
