http://www.elsa.com/international/europe/produkte/mmedia/3drevelator.htm Remember the thread about the 3D display with mechanical scanning ? I have seen these glasses work, they are very good. How about ideas to make an instrument readout 3D using this technology (ir glasses and polarizers on the display elements and a PIC to steer it). Using two LCD displays with polarizers at 90 degrees will already do something (superimposing the images in a mirror or something).
