You may remember the roller-coaster-like sculpture outside the physics and astronomy buildings during Mad Campus at the University of Washington in the fall of 2014. Now, W. Scott Trimble’s Wave Sine has been reinstalled, this time at Occidental Park in Pioneer Square. Take advantage of this beautiful spring weather and go explore. The sculpture will be open for climbing, playing, lounging, and lunch-eating through the end of June. Don’t forget to tag your photos with #wavesine so everyone can enjoy them.
