ABSTRACT:
A method of emitting a visual image from a lighted display includes the step of providing at least one body which is rotatable in at least one rotation direction about an axis of rotation. A plurality of substantially circular image lines are defined, with each image line overlying a respective body. Each image line is concentrically disposed around a respective axis of rotation at a respective radial distance from the axis of rotation. A plurality of light sources are provided and are carried by the at least one body. Each light source is associated with and overlies a respective image line. The at least one body is rotated about the axis of rotation in a plurality of rotations. A rotational speed of the at least one body is determined. A plurality of positions are calculated for at least one of the light sources along the image line dependent upon the rotational speed. The at least one light source is individually switched between an energized state and a deenergized state dependent upon the calculated plurality of positions.
