Very nice job so far, kimncris. Started looking this up after I stumbled across something funny at 7-11 today... I've had a similar feeling about this gauntlet as most of you have been describing. Even if the movie tanks, it still looks cool. 7-11 has got a promotion going with cups and the like, and their "deluxe" version is a big cup made to look like the gauntlet, but around a standard black cup with the title printed on. It looks pretty close to scale, and is fairly well detailed and weathered (could use a repaint, obviously) but one of the neatest features is it's got LED's built into this sucker. The panels on the front of it are rigged to light up already. I'm tempted to grab one and mod it a bit and see if it'll work.
They are $6.99, so I want to do a little bit of digging first and I had the thought to see if anyone here had any similar ideas.
