Quoted from Pinstein:
I bought some real amor off of ebay a plastic skull and some green leds and put together this topper. I have the whole thing assembled on a chunk of 2 x 6 and its heavy. It just sits up there with no hardware as the shoulder armor hugs the head a little on each side. I also put one of those halloween led fire lamps on the back. It was fun to make and definately adds to the stature of the game.
Instead of using that as a topper, you should wear it while playing!
