One of the founders of Wonga has turned his computing skills to a much smaller problem — creating the smallest depiction of a person in history. Jonty Hurwitz, who helped found Wonga by writing the code including the one that quickly determines whether customers should be offered loans, created the sculptures using a tiny 3D printer. Wonga is a British payday loan company that offers short-term credit. The firm operating in the UK, South Africa, Canada, Spain, Germany and Poland, invented fully automated risk processing technology to provide short-term, unsecured personal loans online, including via tablet and mobile app. It has been criticised for its extremely high rates of interest and its debt collection practices.
