ABSTRACT:
A panel display having one or more magnetically responsive changeable indicia and magnetic controls for changing the display of each indicia, desired ones of the indicia being selected and stabilized by rotation or translation of control magnets. The indicia elements are pivotally supported and contain elongated magnets magnetized across their thickness rather than longitudinally, the elongated magnets being centered within the indicia elements along the pivotal axis. Each indicia element is paired with an adjacent movable control magnet which occupies at least two positions for purposes of exercising control of the display. The display is particularly intended for presenting pin fall information and cumulative frame-by-frame scores in the game of bowling.
