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. The process began with 200 cameras taking pictures of a naked model. Those photos were then fed into the printer, which created the sculpture, which is smaller than a human hair and can be comfortably placed on the head of an ant. Multiphoton lithography — which uses a laser to write on the photosensitive material that the statue is made from – helped Hurwitz fill in the smaller details. The pieces are so small that they can only be viewed through an electron microscope and Hurwitz has said in the past that the sculptures are so small that they have been crushed by his friends, after months of work.
