Imagine strolling the pavements of cities like Los Angeles, Madrid or Istanbul and discovering little crystallized geodes hiding in unexpected places, such as within cracks in a wall. Such little treasures do exist thanks to artist Paige Smith, who has made it her mission to brighten up the world's streets, one small geode at a time. Using spray paint on paper or silicon molded resin, she imitates the rugged patterns of minerals to make her artistry. Smith has gained a host of followers around the world from cities she's never even been to, including those in South Africa, South Korea, Jordan and Australia. These followers are creating their own similar geodes, so look out for them, wherever you are!
