Nancy Cervenka was a filmmaker who decided many years ago her true love was film as "material" rather than film as "movie." Her sculptures of twined, twisted and tangled celluloid are things of beauty. See them in an exhibition of her work at Gallery 221 on the Dale Mabry campus of Hillsborough Community College, 4001 W Tampa Bay Blvd., Tampa. Go soon; show closes April 26. Free. (813) 253-7386.
