Three people position themselves in a triangle formation upon the pavement, pulling from their backpacks a speaker each. A loud drone begins to emit from the speakers - three frequencies so closely related that they form an audible beating, changing in pitch and speed as you move from one speaker to another. Soon enough, a man walks past, but stops, suddenly, in the centre of the triangle. He pulls a piece of chalk from his pocket and begins to write upon the pavement, slowly revealing a single sentence... “there have been xx minutes since our last theft”. Upon finishing writing, the man stands up. He moves as if dancing, walking first left then right to admire his handiwork.

 

After a moment, he nods to himself, and proceeds to remove a small polythene bag from his pocket. The drone continues to play - the crowd of onlookers growing larger by the minute, a mass of half-amused, half-confused people. Reaching into the bag, the man retrieves from it 30 individual pound coins, which he then lays in a circle surrounding the text. When the circle is complete, all 30 coins placed ceremoniously upon the floor, the man returns the chalk to his pocket. He admires his work once more before, without glancing at the audience once, he leaves from the direction in which he came.

 

Several minutes later, the music begins to die down. The three people holding the speakers depart one by one, leaving in their wake only a circle of onlookers, forming a circle around some cryptic and vaguely moralistic text, 30 pound coins lying on the ground. After a moment, a young lady kneels to take them money. A child remonstrates her, but she continues. Another joins her, and another, whilst the child is joined by an old man, hand placed firmly against his hip in disappointment. "There taking the money!" he calls, in vain, after the now long gone performer. Several people join him, passing disappointed looks and tuts to those who took the money, now hiding round the corner, wondering what just happened.
