But in this application, the rainbow cursor is turned on deliberately, under user control. This application was created for people who are curious about the rainbow cursor and would like to get a better look at it. It is expected that this application will become increasingly valuable with the arrival of Panther and subsequent OS X updates since it will be much more rare to see a rainbow cursor then.

If you want to get an especially close view of the cursor, position the application window in the middle of the screen and then press Command Option 8 to turn on Aqua magnification mode, and then press Command Option = to magnify the screen. Press Command Option 8 again to turn off Aqua magnification mode.
