Most of us only think about chewing gum on the sidewalk when it sticks to our shoes, but if you live in North London, that gum stain on the sidewalk might just be a tiny masterpiece.

While many people don't notice his tiny city adornments, those who do tend to appreciate the colorful works of whimsy spicing up the otherwise dull city streets.
