Hmm, not lightproof, that kinda sucks. Well, worst case, I'll put some ducting through the intake, bend it 90 degrees, cover it with a stocking and duct tape it. Anything can be done if you just use enough duct tape! I'm not all that concerned with visual stealth. I mean, a gigantic humming...thing...more than 4 feet wide and 4 feet deep and 7 feet tall, if that doesn't arouse suspicion all by itself, what would?
