What is the best way to set up the Screen Screw prank?

For maximum confusion:

• Use a longer interval: Set the timer to 15-30 seconds so the color changes are gradual and the target thinks something is wrong with their monitor
• Add it to Startup: Place a shortcut in the target's Startup folder (Win+R, type shell:startup) so it runs automatically every time they log in
• Let them troubleshoot: The beauty of this prank is that targets often blame their monitor, video card, or display cable before suspecting a prank program
• Watch from a distance: Enjoy watching them adjust monitor brightness, check cables, and restart their computer trying to "fix" the problem
