   Greetings, world! I'm working on some graphics stuff in Turbo C++ 3.0,
and am trying to figure out how to color-cycle the VGA palette in the
standard 320x200x256 mode. (For argument's sake, color-cycling is the
trick Fractint does, especially on the plasma type.) The only problem
is that I am extremely !clue on how to do this. Would some wise soul
please either explain (in newbie terms--I'd rather feel stupid than
remain lost) [:)] how to do this or point me at some sourcecode that's
easily comprehensible? Thanks very much! (In advance, even.)
