Abstract
An image-creating implement includes a plurality of light sources, such as LED's, arranged in a one-dimensional matrix. The one-dimensional matrix includes a vertical column and a plurality of horizontal rows in which each of the horizontal rows has no more than one of the light sources. The implement also includes electronic circuitry which is adapted to blink each of the light sources in a manner such that when the matrix is moved an observer thereof will observe a two-dimensional image.
