The Matatu buses perform several functions for the people of Kenya. They are the dominant system of mass transit for the locals, with routes set up as the market dictates. They serve as group investment enterprises for people of all classes, with these collectives known as Saccos. They’re also a striking example of public art in a city largely clean of graffiti tags or murals. Artist Dennis Muraguri, who features the buses frequently in his work, told me that you’re never truly famous to the locals until you’re featured on a Matatu.
