This weekend, while I was hanging out with friends in the center city of Philadelphia, I found those street arts impressive and interesting. This reminds me of one controversial graffiti artist, Mobstr.
For me, his arts are not only entertaining, but also thoughtful. Painted on the wall of London, it gives busy people a chance to stop for a second to think about life and some trivial things they might never notice before.
Here are some featured arts of Mobstr.
