Once you click the flag, stare at the plus sign in the center. Circles will start to disappear, but they look like they're being replaced with much lighter versions, and if you look directly at it, you won't see it anymore! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This works best in Full Screen Mode, and Turbo Mode does nothing special or different than normal, so don't bother Shift-Clicking the Flag. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ For even stranger effects, press the Space Bar.
