Basket

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 416.5 Hz, 105 cents sharp of G4, the nearest tine on the comb. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Tap it to shake the shells.

A woven basket full of seashells from the beach: sea urchins, sand dollars, starfish and a scallop. Baskets are made by weaving strips of plants, like willow, reed or grass, over and under each other, and people have woven them for thousands of years.

Tap it and the basket shakes: ten of the biggest shells bounce up one after another, spinning, and drop back. A sand dollar is a kind of flat sea urchin; alive, it is covered in short, soft spines that it uses to move through the sand.
