Bring a yes-or-no question to mind. Press and hold the orb to shake it — release when your intention is set. Free forever.
While you hold, the orb records the exact millisecond you began, the millisecond you released, the length of your gesture, and every twitch of your hand across the screen. Those numbers are folded together with the current Unix time and passed through a uniform pseudorandom hash — one of twenty enchanted answers falls out, each with equal probability.
For entertainment only. The oracle is a mirror for your own reflection.
