instructions for a life-size, wearable Iron Man helmet complete with "eyes" that light up. http://www.instructables.com/id/How-to-make…

Following instructables on tumblr is definitely one of the best online-related decisions I've ever made. There's some seriously cool shit that people make. I especially like this particular instructable because I think it could be modified to make similar helmets from video games, movies, etc. Create away!
