Hi Olin, I once saw a design for a 3D display, they had a vertical clear plastic panel, rotated vertically, then projected a scanned laser onto it from the side. It could generate a complete 3D shape, viewable from all directions. The thing I liked was that it could generate a shape with the dimensions quite correct, which looked very handy for CAD model display. Haven't seen much about it since. Maybe this could be done in a lower-res form by using a spinning panel of leds?? That would look very clever. -Roman -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
