I DEMAND THAT YOU ALL HALT! lol, jk. Hmm... before i begin what I have to say, let me note that even when you've been around for a while, check the stickies constantly!!!! Ok, now, I begin. The GUNGNIR helmet.... Lots of ideas have been tossed around.... Koliedoscopes, cameras, magnifying glasses in a stacked apparatus. Whatever happened to simplicity? The answer, is in the stickies
My idea: Make the GUNGNIR the same as you would normally, hardening, etc, however, cut out this part of the helmet circled in red.
Basically trooper114's original idea. Vacuform it, or only cut out the front panel.
Then, follow this tutorial.

However, instead of following the tutorial completely, don't use reflective colors like the tutor does. (you might need to experiment) In theory, this would give an onlooker the idea of a completely solid face, although it is actually see through. Also,people will probably start coming up with very complicated ways of how you might be seeing through the helmet to try and figure it out, not to mention that you won't have to worry about heat, battery life, eyestrain, wiring, power source storage, and budget. The only factor in this solution is that you need to get an airbrush, but lets face it, it'll be a lot easier (and cheaper) to get one of those than to get a camera, rip said camera apart, cut and solder wires, hide them in the suit, create a regulated power source that will power the screen for a long time, figure out how to store said power supply, etc, etc. IDK, sounds like the best plan of attack to me
ON TO THE HAUNTED HELM! Ok, personally, i think you guys are on the right track to the haunted helm, but i was thinking... what if you took out the visor, and instead pepped a skull faceplate that you pep, bondo, and paint, place inside of helmet, and then place mesh in the eyesockets. Then, you could use the jetpack or Jorge's backpack as a water resevior to disguise the camelback, or w/e it is you might use. Then, finally, you can run tubing through the eye sockets so that the smoke comes out of your eyes, as well as from other parts of the skull if you so wanted. Also, this way, if people asked, they could literally reach into the helmet and feel the skull, which would be hard from bondo, fiberglass, etc., mimicking a real skull (which i think would be BAMF beyond awesomesauce) This won't be completely accurate to the actual helmet, but would look amazingly awesome nonetheless. Just my two cents
