Nautilus

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 404.6 Hz, 55 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 startle it: it hides its tentacles, then peeks out again.

A nautilus is a sea animal related to the octopus and the squid, but it lives in a coiled, striped shell. Inside, the shell is split into chambers: the nautilus lives in the biggest, newest one and fills the older ones with gas and a little water to float up or sink down. It has up to 90 small tentacles and swims by squirting water. Animals like it have lived in the sea for about 500 million years.

Tap it and, startled, it jets back a little and pulls its tentacles in behind its hood. It waits, peeks out halfway, then slowly reaches out again.

Made in Splashery. Its code is MIT.
