Eye

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 264.5 Hz, 19 cents sharp of C4. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Tap it to blink. Hands-on: drag on the eyeball and it rolls to look where you pull.

The eye is how we see. Light goes in through the pupil, the black hole in the middle, and a lens focuses it onto the retina at the back, which sends a picture to the brain. The colored ring around the pupil is the iris: its muscles make the pupil smaller in bright light and bigger in the dark.

This eye glances around by itself. Tap it and it blinks, turns to look at you and snaps its pupil small. The Pupil slider sets how wide the pupil is, and you can pick the iris color. People blink about 15 to 20 times a minute, which keeps the eye wet and clean. With ✋ Hands-on on, drag on the eyeball and it rolls in its socket to look where you pull; let go and it glances about again.
