The negative mode I'm referring to is as follows: System Preferences > Universal Access > Switch to White on Black All right. Now here comes the fun part...Make sure your monitor is set with Black on White (i.e. this text is black). Then perform the following process (read first): (1) Point your mouse directly above the "Set Display to Grayscale" option, and relax it on the left side of the "Switch to Black on White" option. Click the option. (2) Just as the screen switches, click on the "Set Display to Grayscale" option. Now you have a black on white negative AND color. (3) Go to System Preferences > Displays > Colors: Set to Millions. I just tried this with Jaguar 10.2.8, I'm not sure if this will work on Panther. Now take a look on MacRumors, your computer, iChat, your dock icons, the three buttons on the upper left corner of each window (oooh, cyan blue and purple), go nuts.
