Snowflake

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 1595.5 Hz, 330 cents sharp of E6, 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 to melt it and grow a new flake. Pick the kind of crystal in the Splash tab.

A snowflake starts high in a cloud, when water vapor deposits as ice onto a tiny speck of dust and grows into an ice crystal. It has six sides because of the way water molecules fit together as they freeze. How cold and damp the air is decides its shape, from simple plates to feathery stars.

Tap it and the arms melt back to the middle, then a new flake grows out, a new pattern each time. In the Splash tab, pick the kind of crystal. In 1885 Wilson Bentley became the first person to photograph a single snowflake.

Made in Splashery. Its code is MIT.
