Cymatica

One of Karel's piano takes plays, and the chord sounding right now excites the Chladni plate modes beneath 160,000 grains of simulated sand — so the standing-wave figure on screen is the harmony he is playing. Conduct it with your body: raise your wrists to drive a higher frequency, spread your arms to ring more modes, lean to sharpen the nodal lines.
