This street Art project is called “Urban Geode” and is done by ‘A common Name’ that started in Los Angeles. They created this “Urban Geode” from paper or resin in 3-Dimensional sculpture forms. The finished shapes looks like geodes, crystal, quartz, or any mineral formation. They fit in every little hole of buildings or pipes of urban infrastructures. Behind “A common Name” and “Urban Geode” project, there is Paige Smith, a freelance artist and graphic designer from Los Angeles.
