At first, there doesn't seem anything unusual about this picture. I mean, it's just a bunch of diagonal lines and a slightly distorted square in the middle - right? Wrong.
Believe it or not, the 4 lines that make up the square are actually perfectly straight. In fact it /is/ a perfect square. For proof of this, the animation will swap between the two frames so you can see the square remains the same.
