Real Sunflower

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 404.0 Hz, 52 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 make it nod; drag to turn it.

A real sunflower, captured from photos and drawn with splats. The big yellow head is made of hundreds of small flowers; the dark center ones turn into seeds in a spiral pattern. Young sunflowers follow the sun across the sky, then stop and face east.

Tap it and the sunflower nods and settles. Drag to circle it and look at the petals, the seed disc and the green stem.
