Tap-Tap: Four-Wheel Art in Haiti

PORT-AU-PRINCE, HAITI - JUNE 24: Tap-tap buses pass through the downtown of Port-au-Prince, Haiti, 24 July 2008. Tap-tap vehicles serve as public transportation in Haiti. They are private, operate over fixed routes, departing only when full. Tap-taps are decorated with bright and shiny colors and with a lot of fancy designed elements. There are scenes from the Bible, Christian slogans, TV stars or famous football players often painted on a tap-tap body. Tap-tap name comes from sound of taps on the metal bus body signifying a passenger's request to be dropped off. (Photo by Jan Sochor/Latincontent/Getty Images)
