Abstract:
A method of emitting a visual image from a lighted display, said method comprising the steps of:providing at least one body which is rotatable in at least one rotation direction about an axis of rotation;defining a plurality of substantially circular image lines, each said image line overlying a respective said body, each said image line being concentrically disposed around a respective said axis of rotation at a respective radial distance from said axis of rotation;providing a plurality of light sources carried by said at least one body, each said light source being associated with and overlying a respective said image line;rotating said at least one body about said axis of rotation in a plurality of rotations;determining a rotational speed of said at least one body;calculating a plurality of positions for at least one of said light sources along said image line dependent upon said rotational speed;individually switching said at least one light source between an energized state and a deenergized state dependent upon said calculated plurality of positions; andremotely transmitting a digitally encoded version of the visual image to said electrical controller.
