Evan from Williams Lake, BC has created his own 3D LCD monitor by manufacturing the Lenticular screen that sits in front of the display. Evan's process involves deforming a Lexan sheet with the aid of a CNC milling machine by dragging a special carbide tool over the plastic.
Writes Evan; "I decided to see if I could produce a lenticular lens with sufficient accuracy and suitable focal length to make my own stereographic display. This is an ongoing project but this is the first attempt out of half a dozen that actually works. I ran into a number of issues not the least of which is that the dot pitch of my monitor isn't exactly as advertised. The lens elements must line up all the way across the display or the image will not appear correctly."
