4About it
In 1787 Ernst Chladni sprinkled sand on a metal plate and drew a violin bow along its edge. The plate shook, and the sand jumped away from the places that moved and gathered on the lines that stayed still, a different picture for each pitch. Those still lines are called nodal lines.
Tap to bow the plate: it hums, and every grain hops and slides until the figure appears. Tap again to stir the sand up. Mode picks the pitch and the pattern; Sand colors picks one color, a few colors, or a flag's colors.
Or sing to it, or open a song: the note it hears rings the plate's nearest mode, and the sand sets off for that figure at once; a new note moves it on, and silence leaves it put. A song's strongest pitch, moved by octaves into the plate's range, plays it as the song goes, and the file stays on your device. This splash uses the classic square-plate model, cos(nπx)·cos(mπy) ± cos(mπx)·cos(nπy) = 0, with a pitch that grows with n² + m².
