Cyclicality is an interactive light sculpture composed of 11 illuminated, reflective crystal forms inspired by the natural beauty of Sioux Quartzite. Created as a site-specific artwork by Jen Lewin, the piece invites viewers to explore the flow of color and light through touch and proximity.

Three interactive pedestals allow participants to transform the installation—shifting color palettes, the animation speed, and the rhythm of light. Drawing from the ever-changing landscape of Sioux Falls, Cyclicality reflects the region’s geologic story of erosion, transformation, renewal, and enduring natural wonder.
