by Joshua Allen Harris

Dan Steinhilber works with all kinds of everyday materials and objects like trash-bags, bottles or paper-cloth-hangers. He uses them as modules or media to create abstract organic sculptures.
Street artist Joshua Allen Harris even brings his creatures made of garbage bags and tape to life.
He tapes them to a sidewalk grate and every time the subway passes the underground exhaust inflats and animates the sculpture that first just looked like ordinary trash on the street.
