There's a lot of sound surrounding us. A busy city is not a quiet place. Cars and trucks produce sound, people produce sound, but some of it is really just pollution. Motor scooters with annoyingly loud exhausts, kids on the train listening to urban beats from the thin sounding speakers of their mobile phones, it's a pathetic sight.

What can you do about it? Well, accept it if you want to survive everyday city life, or dance your feet off like this man does. A subtle and fun way to express your discomfort, isn't it?
