Highest resolution that _I_ could afford at the time, on PC, was 1280 x 800, which was well short of a megapixel. (B&W Amdek 1280, with proprietary video board, but did have drivers for Windows 3.00, Ventura, Paintbrush, etc. By the time that Windows 3.10 came out (fall 1991), support was already crumbling) I warned you that it was CRUDE, . . . You looked into a dark cabinet, in which there was a moving mirror, reflecting a CRT. The image would change according to the position of the mirror. When it was moving fast enough, persistence of vision would give you a visual image in which parts of the image were actually different distances! I think that the images were chosen for maximum suitability. I never saw a commercial implementation attempt. -- Grumpy Ol' Fred cisin at xenosoft.com
