ABSTRACT:
An irridescent or luminescent drawing or sketching device that has a housing having a window therein, in which there is disposed a generally transparent imaging plate having an irridescent dye and disposed above an opaque pliable plastic sheet. Application of pressure will cause the opaque sheet to adhere to the imaging sheet at the points of applied pressure, causing an irridescent or luminescent image to appear at the imaging surface. Pressure is applied by a courser which is confined within intersecting slots of a pair of crossing courser arms whereby the movement of the individual courser arms along an X and Y axis causes the courser to translate accordingly. Included is an eraser disposed between the opaque sheet and imaging sheet to effect separation thereof to erase any image formed on the imaging sheet.
