Flasher

Flasher is a hidden prank program that allows you to flash any image to the computer screen, almost like a subliminal message!

Flasher supports JPG, BMP, EMF, WMF and ICO formats. All you have to do is specify the image you want to flash and the amount of time between flashes. When the software is not flashing the image to the screen, it hides itself within Windows until the next time it needs to flash.
This is a great prank to play on your friends. Imagine flashing the logo of the opposing sports team or a photo of their ex. The possibilities are endless so download Flasher today -- it's free.
