wow, this is really good art. I envy the places that have this type of art in the streets. You should start a regular post, where you travel around your city, and map out all the interessting arts, map them, write something about them, and after that, you find a person who know computer stuff, then ask him to make an app called "street art" or something like that, and sell it to the municipal, or go to the free marked :) cool pictures!
