Libyan graffiti artists are taking advantage of newfound freedom to make fun of ousted leader Muammar Gaddafi on the streets of Tripoli.Libyan graffiti artists are taking advantage of newfound freedom to make fun of ousted leader Muammar Gaddafi on the streets of Tripoli.For 42 years, the authoritarian leader banned writing or drawing on public walls. Artists are now expressing themselves throughout the capital of 2 million people, and their favorite topic is Gaddafi and other former members of his regime on storefronts and office buildings.One picture mocks Gaddafi\'s habit of calling himself the king of kings of Africa by calling him the \"monkey of monkeys of Africa.\"Another shows the longtime leader\'s public relations officer Youssef Shakhir with a rat\'s tail and holding prayer beads, because people said he always held them in appearances.Gaddafi, who remains on the run after revolutionary forces swept into Tripoli on Aug. 21, also is shown with his trademark curly hair, but the mural calls it \"barbed wire hair\" instead of using his popular nickname \"frizzhead.\"
