Ben Koracevic, aka The String Art Guy, of Stringometry Art Studio, creates beautifully intricate and detailed art using just nails and string. He quit his day job, cashed in his life savings, and began weaving portraits of well-known figures such as John Wick, Dwayne "The Rock" Johnson, The Lion King, and the Joker. His process to make one piece can take up to 500 hours.
