The area of Hoxton, in and around Brick Lane, is brimming with murals and street art that seem to integrate perfectly with both the industrial and natural surroundings. (Case in point: That tree is actually real. When I first saw it, I thought it was part of the painting!) You'll surely spot a Banksy (or a copycat), along with larger-scale pieces that clearly took ages to complete. Just wander around and take in the myriad color pops and techniques. Expect to be inspired.
