Saturn

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 546.0 Hz, 74 cents sharp of C5, 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 send ripples across the rings.

Saturn is the sixth planet from the Sun, a giant ball of gas with the brightest rings in the solar system. The rings are made of countless pieces of ice and rock, from specks of dust to chunks as big as a house, and they are very wide but mostly very thin.

Here the rings turn all the time, the inner rings faster, as real ones do, with dark spokes and bright clumps that show the motion. Tap it to send two sparkling waves rippling out across the rings. Saturn is so light for its size that it would float in a big enough bathtub of water.

Made in Splashery. Its code is MIT.
