In an artistic and tactile manner, Tectonic Basin helps demonstrate principles of geology, erosion, chaos and more. Fine grained sand covering a low-frequency vibrating base plate causes the sand to move and settle in unpredictable ways that resemble the shifting sands of a desert. Visitors can spread the sand with their hands and watch the pattern reform within a few seconds.
