This image was taken in central Barcelona from the rooftop of the Grand Central Hotel. At first glance, you'll notice symmetry in the picture. That's because I've mirrored the image, and then painstakingly altered it so that the equality is incomplete. In effect, I've taken something that was perfectly reflected and added randomness.
There are plenty of mirrored artifacts, but depending on how you look at it, it might play tricks on you. Our brains quickly suspect its a mirror, and then our eyes begin looking for proof. Depending on where in the image you look, it may not confirm your first impression.
The photo is an exercise in abstraction and deception. It's a time-consuming exercise to produce, but it's fun at the same time. My purpose is to hint at one thing while throwing you off the trail and forcing you to figure it out. I hope you don't mind a little harmless deception in the name of fun.
