Potted Cactus

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 491.8 Hz, 93 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 open a ring of flowers around its top.

A cactus is a plant built to live where rain is rare. Its thick green stem stores water, and its spines are leaves that have changed shape: they shade the stem and keep hungry animals away. The stem, not leaves, does the work of turning sunlight into food.

Tap it and nine magenta flowers open one after another in a ring around the top, then close again. Many cacti bloom for only a few days a year, and some flowers open for just one night.
