Skate for good: Afghan tricks come to Joburg

After months of hard work, Skateistan Maboneng, Johannesburg, is in the final stages of construction. It's a project that originally began in Kabul, Afghanistan, when Australian skater Oliver Percovich arrived in the city with three skateboards. Like a modern Pied Piper, he soon had children following him around the city as he taught them how to skate.
