Plexiglas is opaque perspex - the type of stuff used on the surface of light boxes (by pcb makers) or for outdoor illuminated shop signs. It is the same color right through. Lithophanes are made by converting a photo or other image to a 'height map' which is then used to produce the GCode. 'Mach1 filter' will do this job converting .bmp or .hpgl files to GCode (it can be downloaded from the Artsoft site). The height map is used in reverse (negative) so that white is cut deep and black is cut shallow, if at all. The litho is back lit, the ones shown above are just stood on a window sill and that does it just fine. Please check out my website for further details http://www.cooperman.talktalk.net
