The fortune-teller of every 90s sleepover, rebuilt from photos of real ones down to the answer die adrift in its blue ink (turn your sound on). Ask a yes-or-no question and shake it: drag the ball back and forth, or just tap it. It turns its window to you, and one of its 20 answers floats up out of the murk - ten say yes, five say no and five won't commit. Drag beside the ball to look round it. On a computer, Space or Enter shakes it.
