The Fridge (thefridgedc.com) is a friendly gallery in Capitol Hill that specializes in street art. Part of the fun is finding it. Follow the murals and graffiti into the alley beside the oyster shop on 8th St SE | DC
The graffiti art here states the political message that we should appreciate the revolution of others to how the government should be changed, but the reason it is backwards, is because the situation itself is backwards. The government goes against the opinions of others.
David Walker is a good example of style repetition. He has a unique style that can be identified throughout his works. The repetition is in his colour theme and applications of colours used to structure his art. The colours are well defined and strongly stand alone though also create a well structured shading to define the image being created. His art is a good example of contrasting colours used to compliment each other in the big picture of things.
