Butterfly

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 456.8 Hz, 65 cents sharp of A4, 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 flutter faster. Hands-on: pick it up and let it flutter off.

A butterfly is an insect with four large wings covered in tiny, overlapping scales, and the scales make its colors and patterns. Every butterfly starts life as a caterpillar, which sheds its skin to become a pupa, called a chrysalis, before emerging as a butterfly. Some colors, like the shining blue of the blue morpho, come from the shape of the scales, not from any paint-like color in them.

It flaps its wings slowly all the time. Tap it to flutter, beating its wings faster and wider for a moment. Pick a monarch, a blue morpho, a swallowtail or a rose butterfly in the Splash tab. With ✋ Hands-on on, pick it up and it flutters hard on your finger; let go and it flutters off and settles back to hovering near where you left it.
