I went to NYC for a day visit with a friend who had never gone. While visiting and showing her around, we saw a street artist working so I had to watch. In 8 minutes he created this picture. I wanted to support him so I bought it for 20$. I think it looks pretty incredible for as fast as he did it. I also took a video of him painting another piece very similar. You can see in the video the different tools he used, none of which consisted of a paint brush.
