The Orlando Museum of Art adds a musical component to enhance the viewing of ''M.C. Escher: Rhythm of Illusion." The prolific Dutch artist (1898-1972), known as the ''Master of Symmetry," played with perspective, patterns, and visual illusion, creating 480 lithographs, woodcuts and wood engravings, and more than 2,000 drawings and sketches. For the traveling exhibit, the Portland Art Museum in Oregon selected 180 prints and drawings from the 1920s to 1960s and organized them in six themes. For Orlando, composer Stella Sung, a music professor at the University of Central Florida, and sound designer David Wallace adapted computer and digital technology to weave a soundscape that Sung calls ''immersive ambience."

The Winston Cup Museum fills the gap for NASCAR fans who want more than just the roar of the race circuit. The longtime dream of businessman Will Spencer became reality in May after a six-month makeover of a former auto dealership. Spencer, owner of JKS Motorsports and provider of signage for Winston Cup/NASCAR races since 1971, is an avid collector of race cars and memorabilia. The museum centerpiece is a three-wall mural depicting the circuit's history and the 33-year sponsorship by R.J. Reynolds Tobacco Co. Permanent displays of helmets, posters, uniforms, and trophies focus on a trio of famous races: the Winston Million, Winston No Bull 5, and The Winston.

The Friends of Laurel Hill breathe new life into the city's 1836 landmark cemetery with walks and other programs to preserve and restore the 95-acre site. A National Historic Landmark, Laurel Hill is the nation's second-oldest garden cemetery, opening five years after Mount Auburn in Watertown and Cambridge. Like Mount Auburn, Laurel Hill is rich in history, sculpture, and architecture in a hillside setting overlooking the Schuylkill River. It was neglected in the last century until the nonprofit Friends group was founded in 1977 and rekindled interest in restoring the final resting place of the city's industrialists, political figures, artists, soldiers, and other notables. Upcoming walks include ''Philadelphia's Industrial Magnates" (Aug. 14), ''Dead White Republicans" (Sept. 11), and Halloween tours (Oct. 28-30). The Friends also revived the ''Gravediggers' Ball," a black-tie dinner-dance benefit held in a heated tent on the grounds (Oct. 22).
