I find it to be pretty cool that different people looking at the exact same picture are seeing different things. It's kind of like that shadow dancer gif rotating clockwise or counter-clockwise, except it's even weirder.
What confuses me more than the picture itself is the face that like half of the people in this thread seem legitimately upset by it. Like, is this actually making you angry? I guess it's the cool thing to disparage things that become popular on the internet.
No, we can have a 30 page thread with people arguing about whether soup is a food or a drink, but this, this has gone too far.
