Why the sand does this

When a metal plate vibrates, most of it moves, but some lines stay perfectly still. Sand bounces off the moving parts and comes to rest on those still lines. The shapes it draws are called Chladni figures, after Ernst Chladni, who showed them in the 1780s. Every pitch draws a different figure.

Here each mood plays its own note on a simulated square plate, so each one leaves its own trace.

Your mood, every day

In Moodera you tap the orb and your mood draws itself in sand like this. Then music made for that moment begins, and every day you listen becomes a star in your own sky.
