ABSTRACT:
An image generating board apparatus is provided, including an image display board having an array of peg ports, pegs formed of translucent and colorless material rotatably fitted into each of at least two of the peg ports, each peg having a peg distal end which is substantially planar and is fitted with a polarized film section, and each peg having a peg proximal end, a light source adjacent to the display board and to the peg distal ends, a polarized film sheet mounted to extend between the light source and the peg distal ends and with its polarization axis angled relative to the polarization axis of the film sheet, and a tape sheet mounted to pass between the film sheet and the peg distal ends, so that light from the light source shines through the film sheet, through the tape sheet, and through the film sections at the peg distal ends and isolates and selectively passes into each peg an isolated wavelength of visible light from the light source, the isolated wavelength illuminating each peg with a color corresponding to each isolated wavelength, and so that rotating any given peg causes the film section of the peg to shift its relative alignment with the film sheet and the tape sheet polarization axes, thereby shifting the wavelength isolated and projecting into the peg to a different illuminated color.
