South Africa's 'fun sock' entrepreneur

After selling an app he had created to a social media site, 31-year-old Nic Haralambous had enough money to invest in one of his passions - quirky, colourful socks... some of which are made of bamboo.

He partnered with his girlfriend, alongside two foreign investors, and together they have created a retail product that is walking the streets from Cape Town to New York.
