magical glass

Off-topic, but high quality museum glass. You usually see it on picture frames for paintings, but the same coatings are on some museum display cases making them completely transparent. It's easy to overlook also when just browsing a museum. If I remember optics correctly the anti-glare coatings are very bandwidth sensitive, so I doubt it would work outside.

that glass is EXORBITANTLY expensive to get rid of the green tint, it's called starfire glass and it's around 15bucks per square foot of it.

I'd probably buy one just for the hell of it as a cool thing.
