Robyn Davidson tells Jo Fidgen about walking 1700 miles across the Australian outback with four camels and a dog for company.

Also on the programme: Mayam Mahmoud, a head-scarved Egyptian teenager who's making a name for herself as a rap artist; Gary Slutkin, an American doctor who cures violence by treating it like a contagious disease; and Thierry Noir, a French artist whose paintings on the Berlin Wall now fetch millions of dollars.
