Street artists Astro and Kanos have come up with a way to write graffiti and paint massive murals without defacing public property, thereby also keeping the popos happy. The technique called Cellograff involves wrapping and stretching sheets of cellophane around trees and poles to create a makeshift canvas. This allows a street artist to express himself to his heart's content and to leave his mark in a city without breaking any laws. Astro and Kanos have been using this method since 2009. Check out a video of the two pioneering artists in action below:
