Wave Sine in Occidental Square

Artwork - Wave

According to Wikipedia, a sine wave is “a mathematical curve that describes a smooth, repetitive oscillation.” In 2016 at Occidental Park, it described a 75-foot-long, nine-foot-tall ribbon of wooden boardwalk unravelling along a roller-coaster outline. This popular installation was brought in by DSA in coordination with artist W. Scott Trimble and provided plenty of space to run on, climb or take a lunch break. Visitors jumping from wave to wave or relaxing on its gentler slopes demonstrated how art like the Wave Sine invites people into public spaces and creates interactive, family-friendly activities downtown.
