Wizard's Orb

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 580.3 Hz, 21 cents flat of D5. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Tap it to cast a spell: sparks spiral out and runes circle the orb.

A wizard's orb is a glass ball from stories of magic, where a wizard gazes into it to see faraway places or the future. This one sits on a stand, with glowing magic swirling inside. Runes, the letters of old alphabets once used in northern Europe, are often carved on magic things in stories.

Tap it to cast a spell: a flash of light fills the glass, the swirl spins up, sparks spiral out in five arms, and a ring of runes rises and circles the orb before it fades. Pick the color of the magic in the Splash tab.
