It's alive! Alive! Answered
I've been wanting to build a Stargate helmet for a very long time but there was no way I could spend the cash to sculpt one in clay and do a fiberglass casting in a silicone mold so I had to improvise by using cardstock, paper mache and foam. I really wasn't going for screen accuracy as this is intended to be a costume helmet instead of an accurate replica.
When I set out to build this I wanted it to be light weight, low cost and most importantly I wanted it to move. I still have quite a bit of work left to do- I still need to add the glowing eyes and do some filling, sanding and detail work plus paint. Watching it move for the first time was just awesome. :)
