Your eyes may have grown accustomed to the graffiti and other forms of visual street arts. They may not be so shocking or provoking by now. You may pass by them without even noticing that they’re there. When this is happening, it’s like a sign that there is a need for re-invention. And this is exactly what Cayetano Ferrer has come up with in his project City of Chicago. His artistic stickers are placed in different spaces, perfectly matching the surroundings, giving an impression of dissolving landscapes. This optical illusion will make you look twice next time you pass by a street sign.
