The Stonestreet Diamond Sign at 209 East Broad Street is getting a updated with the help of the mOb Studio. Students in the studio worked individually to discover new material and surface treatments for acrylic. On Friday, they worked together in teams to layer the new faces of the sign with stenciled shapes and the building address. They carefully choreographed their movements around each other and the wet paint in order to shield overspray and avoid scuffing recently painted motifs.
