Visiting artist Stephan Wanger, right, and volunteer Trey McDowell, left, sorted Mardi Gras beads by color Tuesday during the first of a series of workshops in which children and adults are invited to join Wanger in creating elaborate mosaics that depict scenes of Natchitoches.  Bead Town workshops are being held Tuesdays through Fridays in Northwestern State University's Hanchey Gallery, where a selection of Wanger's work is on exhibit through Aug. 18.  Wanger will live in Natchitoches for six months while the murals that commemorate the Natchitoches Tricentennial are in progress.  More mosaics are on display at the Natchitoches Arts Center, 716 Second St. To participate in a workshop, call the Natchitoches Main Street office at (318) 352-2746.  Private and/or corporate workshops are also available. Wanger's work is also the subject of a documentary currently being filmed by Cataclysm Pictures.
