The three grey three metre steel pigeons created by Gerhard and Maja Marx (2009) look as if they have been fashioned from origami. As Past Experiences' tour guide Jo Buitendach says: 'Most statues have pigeons that sit and poop on them. These pigeons were made for that.' The sculptures have metal rods so that live birds can roost on them, encouraged by food left by the local community. In an interview published by the Johannesburg Development Agency Gerhard Marx said: 'Having the pigeons sitting on the sculpture [is] part of the choreography of the sculpture.'
