Some street artists have become famous. Here are three stars of the street art world:
Os Gemeos are twin brothers from Sao Paulo in Brazil. They paint big, colourful pictures of people on buildings. In 2007, they painted a castle in Scotland!
Blek le rat is from Paris. He is famous for painting pictures of homeless people in big cities.
Faith 47 is from Cape Town in South Africa. She paints big, colourful pictures of people and animals. She likes painting in different places and you can find her work on pavements, postboxes, buses and, of course, on walls!
