Windmill

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 524.1 Hz, 3 cents sharp of C5. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Tap it for a gust of wind that spins the sails hard.

A windmill uses the wind to do work. The wind turns its big sails, and gears inside turn that into the turning of heavy millstones, which grind grain into flour; some windmills pump water instead. In the Netherlands, windmills pumped water out of low land for hundreds of years, so that people could live and farm there.

Its sails always turn in the breeze. Tap it for a gust of wind that spins the sails up hard for three extra turns, then they slow back to their steady pace.

Made in Splashery. Its code is MIT.
