A grid of six scientific diagrams illustrates optical phenomena through concentric patterns and radiating lines rendered in warm golds, cool blues, and deep blacks against dark grounds. Each panel presents a different manifestation of light interference and diffraction, from kaleidoscopic rings to angular light-path tracings, capturing the precise mathematical beauty of 19th-century physics visualization. Printed to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
