Actually, it's as glamourus as it sounds, nor as easy or useful. To display a 3200 color pic. Your CPU has to spend ALL of it's time switching the color pallete3200 colors (and see it at the same time), that would be impossible (unle ss you have a TWGS (I -think- that would make it possible). because any code that would read the mouse or call a toolbox routine, would throw off the timing of switching the colors. The way they 3200 color deal works is, while the electron beam in the monitor is scanning it's way accross and down the screen, the computer is changing the color pallettes and timing is CRUCIAL in doing thi s, that's why having the program do anything besides displaying the picture wou ld be extremely difficult, if not impossible. Also, the computer is limited in the way the 3200 colors are displayed. You cannot have any pixel on the screen set to any one of the 3200 colors you want. It's similar to the way a 256 color picture is displayed. With aEach horizonta l line has it's own set of 16 colors and ONLY that set of 16 colors may be disp layed on that line. (16 colors per line times 200 lines = 3200colors). Hope this explains it a little (I may be a little off on some of my technical details, but I know I'm close.)
