This is a greenhouse in Amsterdam built by artist Victor Engbers using uranium glass. Uranium glass (aka Vaseline glass) is glass made with a small amount of uranium in it that makes it glow bright green under UV light. In this case, Victor filled the greenhouse with blacklights to really make the glass shine. Me? If I had a greenhouse I'd fill it with plants, because that's what greenhouses are for. Do you even know what you're doing, Victor?
Keep going for a couple more shots.
