On April 11th 2002, 500 voluntiers were called in order to form a line to move a sand dune situated in the surroundings of the city of Lima. This human comb progressed pushing forward a certain quantity of sand with shovels in order to move the dune from its original position. The actual displacement was of an infinitesimal proportion, but not its metaphorical resonance.
This project was presented at MoMA in 2011.
