This fall's blockbuster show won't be inside the Philadelphia Museum of Art but outdoors, on the Benjamin Franklin Parkway. It's "Open Air," a public-art project by the Mexican-Canadian artist Rafael Lozano-Hemmer. The nighttime light show, created by 24 powerful searchlights placed along a half-mile section of the Parkway, is both technologically sophisticated and participatory - a cellphone app will allow members of the public to alter the position and intensity of the lights. (The artists also, after protests from bird lovers, has promised modifications to decrease the lights' effect on migrating flocks.)

"Open Air" was commissioned by the Association for Public Art, formerly the Fairmount Park Art Association. Is it really art or merely a spectacular entertainment? We'll find out at 8 p.m. Thursday, when the show opens. The lights will be on for three hours nightly through Oct. 14. Learn more at http://openairphilly.net.

If outdoor art doesn't appeal, plenty of traditional museum stuff awaits you through the end of the year. Keep reading.
