Music thumping through your ribs. You're wedged in a human traffic jam where everyone is dancing, lunging and swerving with no indicators. Drinks fly. Sweat rains from the ceiling. In your hands: a camera with a comically large lens, worth three times your rent.

You move like a ninja waiter carrying a full tray of beers through Oktoberfest in Munich. You have one job: find that precious split second and catch it before it's gone.
