Liammmin, a redditor, caught this incidental eyeball in a swirling drain. The origin story has a good moral: "My friend said something around the lines of 'Liam, you take too many photos.' So I ran around the room taking photos of everything and showing him all of them, then this happened and we got spooked." -- the moral being, "If you want to double your success rate, triple your failure rate."
