The 200-year old studies by Chladni, of the sand figures of vibrating plates, live on today in the investigation of the wave mechanics of nonintegrable systems. This talk gives will survey the contemporary mathematical analysis of the wave-function statistics of the billiard problem, uncovering the manifestations of classical chaos in the wave-mechanical world. Some of the experiments of recent years will also be surveyed. The illustrations show the continuing Chladnian splendor of the current-day subject.
