Abstract
A method of creating an image involves providing a plurality of light sources arranged in a one-dimensional matrix. The one-dimensional matrix is made up of a vertical column and at least two horizontal rows in which each of the horizontal rows has no more than one of the light sources. The light sources are blinked at their safe maximum current for at least two image_times that are within the range from about 30 milliseconds to about 200 milliseconds without damaging the light sources or electronic circuity controlling the light sources. Each of the image_times includes two or more display_times that are equal to LED On time. The light sources are moved relative to an observer, such that the observer will observe a two-dimensional image.
