Its note

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 635.8 Hz, 63 cents flat of E5, 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.

About it

A sea urchin is a round, spiny sea animal, a relative of the starfish. Its spines protect it, and between them it has long, thin tube feet with suckers that it uses to walk and to hold on. Its mouth is underneath, with five strong teeth for scraping seaweed off rocks.

Tap it and its spines sweep around it in waves, each tilting on its base, while pink tube feet reach out, and it creeps a little way to the side and back. Pick a purple, black, red or green urchin in the Splash tab.
