Who knew a photocopier could be used as an art medium? This will be the focus in the Lyman Allyn Art Museum’s newest exhibition, “Pati Hill: Photocopier, A Survey of Prints and Books (1974-83).” The show, which explores the works of the late photocopy artist, writer and former Stonington resident Pati Hill, features 120 photocopied works on paper. The images range from everyday items such as a hair brush and thread spools to bizarre subjects like a dead fish. The show opened on Saturday and runs through March 4. The museum is at 625 Williams St., New London. Hours are 10 a.m.-5 p.m. Tues.-Sat., 1-5 p.m. Sun. Admission is $10 adults, $7 seniors and students (over 18), $5 students under 18, $7 active military personnel, and free for children under 12; (860) 443-2545, www.lymanallyn.org.
