Crystal Ball

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 554.2 Hz, 99 cents sharp of C5, 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 to gaze into it. Hands-on: lift the ball off its stand, roll it, set it back.

A crystal ball is a ball of clear glass or quartz. In old stories, fortune tellers gaze into one to see visions of what is to come. A real clear ball also works like a lens: look through it and you see the room behind it, small and upside down.

This one is filled with glowing mist. Tap it and the mist whips around and thins, and a glowing sign rises out of it, turns once and fades: a star, a moon or a heart in turn. Pick the color of the mist in the Splash tab. Sparkle adjusts the sparkling effect in the ball. With ✋ Hands-on on, lift the ball off its stand and set it down or roll it on the table, its mist swirling inside; bring it back over the stand and it settles into its cup.
