Escopetarra
López made five escopetarras, four of which were given to Colombian musician Juanes, Argentine musician Fito Páez, the United Nations Development Program, and the city  government of Bogotá, while one was kept for himself. Juanes later sold his escopetarra for US$17,000 at a Beverly Hills fundraiser held to help victims of anti-personnel mines, while the escopetarra given to the UN was exhibited at the June 2006 of the UN Conference on Disarmament.
