If the Second Annual Mask Design Competition is anything like last year's event, ghoul and goblin masks will be the least impressive of the bunch. In the Broward Community College Arts Department, more than 800 white plastic masks were distributed to the faculty, staff, and students, who were expected to turn the masks into works of art. Last year Cathi Leisek, director of the college's sculpture program, took as her theme environmental destruction. On the mask she painted smokestacks, which spit out black clouds of smoke made from soft fabric. Dead birds (fake, of course) dangled from the mask, and chandelier crystals were placed on top to represent acid rain. Another mask, embedded with cigarette butts and looking more like an ashtray, served as an antismoking statement. "Some of [the masks] are sound- and video-activated," says Leisek. The results of this year's competition are on view through November 6 in the BCC Visual Arts Department, Bldg. 3, 3501 SW Davie Rd., Davie. Admission is free. Call 954-475-6506.
