I found this artist that makes art on dirty car windows. I found this really inspiring because normally if your car was dirty you would wash it, but this person thought of the dirt differently and decided to do drawings in it. By wiping more dirt of in the darker parts and leaving more dirt on in the lighter parts. To get the tones in between the dark and the light shades, he wiped out tiny bits of the dirt, to give it a darker gray color. There are a tone of different pieces he has done, you can see some of them down below, or you came see them all on his website Here. To make these pieces of art he first used his finger but then started to use his paint brushes. Not only has he done this art on cars but he has done it on glasses, and done big dirt murals on store windows.
he has also played a role in a music video
