I first ran into this art while walking around Jackson Square down in New Orleans. On the street were artists. Although this video is from a guy your age, the guy I saw was a little older. In about 20 minutes, he would take spray paint, tupperware lids and create these fantasy galactic landscapes. I was absolutely amazed and would spend hours watching the creation and sales of these works. After visiting some other cities, I found out that it was a bit more common to see street vendors doing this. I don't care how popular it is-- it will always be interesting to me.
