What is the best way to set up the Flasher prank?

For the best results:

  • Choose a funny image: Use a photo of a coworker, a silly meme, or something unexpected
  • Set a long delay: Use 60-120 seconds so the flashes seem random and unpredictable
  • Hide the executable: Place it in a folder the target will not check, or add it to their Startup folder
  • Rename the file: Rename the executable to something mundane so it does not stand out in Task Manager
