This ephemeral sand-scape artfully demonstrates the universal principle of entropy through a fascinating, ever-changing microcosm of natural elements. Simply rotate the glass ring and watch as delicate drifts of light and dark sand shift into deserts, mountains, clouds, rain, oceans and smoke, all ebbing and flowing into one another. There is an eternal yet fleeting quality about this interactive art, and the sparkling sand will mesmerize as it shapes a tiny world right before your eyes. Created by Klaus Bosch, this inventive artwork will bring a calming, natural presence and a sense of wonder to your office or home. Handmade in Austria.
