I made them years ago...even had a tutorial up here for a while. They're both made from Cooper SK2000 hockey helmets...used to be able to find them for $30-40 on E-bay. The helmet design fluctuated from scene to scene a little in the movie, but I used a lot of screen shots and publicity stills to try to get the circuit pattern as close as possible. I hand drew the designs, scanned them, and overlayed them using Photoshop. Printed them off on adhesive paper, cut, and adhered. The helmet needs a little prep work with Bondo first and you have to make a foam insert...I used a cut up kids' playground tile for that. I'm about 4 computers past the one I used for these, and although I know I probably have the .jpg files somewhere, they aren't readily available.
