Soweto street artist tries to educate through his work

In the South African township of Soweto, a new generation of artists are exploring their country's history through the art of stencilling and graffiti.

Nkululeko Mhlangu creates images of key political figures like Nelson Mandela, but also musicians, artists and other black icons, to inspire those around him.

He argues that his work documents the history of black people in South Africa, providing education for people who see it.
