Street painting, also known as pavement art, chalk art, and sidewalk art, is the performance art of rendering original and non-original artistic designs on pavement such as streets, sidewalks, and town squares with impermanent and semi-permanent materials such as chalk. The tree dimensional phenomenon started way back in the 16th century and the artists back then were known as street painters. Now it has a variety of names like 3D art, sidewalk art, and chalk art. Regardless of the names, all viewers come to one important conclusion; 3D art is mind blowing!
