Sometimes one David just isn't enough. Michelangelo's David, he of the giant hands, has been around for 500 years now. To celebrate this momentous occasion, a bunch of local artists have each made new art that incorporates, in one way or another, images of Michelangelo's famous sculpture. Some pieces are heartfelt tributes. Some are hilarious satires. Many are impossible to categorize. A reception for 500 Davids will be held Friday, Feb. 4, from 5 to 9 p.m. at Galeria Artopia (5100 Constitution NE), a gallery located in the home of Allan Rosenfield. The show runs through March 12. 254-0504.
