Sunflower

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 488.5 Hz, 81 cents sharp of B♭4, 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 bring out the sun. Hands-on: push the head and it nods on its stem.

A sunflower's big head is not one flower but many: the dark middle is packed with hundreds of tiny flowers that each become a seed, and the yellow petals around the edge belong to flowers of their own. The seeds grow in spirals that curve both ways.

The head nods gently at rest. Tap it to bring out the sun at the top left: the head turns up to face it and its petals spread wide open; then the sun goes in, the head turns back and the petals lift again. Young sunflowers really do follow the Sun, turning from east to west during the day. With ✋ Hands-on on, push the head and it nods on its stem, petals and all; let go and it springs back and wobbles.
