This is a little trick I’ve pulled on some family members in the past and most recently on my boss for April Fools. All you need for this is a working version of Adobe Flash.

If you cant see whats happening, basically the effect is that the desktop looks like its moving back and forth. 

So all I am doing here is tweening 2 instances of the desktop (which i Print Screened) over a static instance. Then all you do is full screen the SWF on your targets desktop. You can do a lot with this little gag including; hiding the users mouse, popping up text and moving icons at will.

Back when GMail did their YouTube contest, i used this gag to simulate the envelope moving across multiple screens.

A few things to remember when doing this are:
Make sure your stage width and height are the same as the target monitor
I use PNG’s of the desktop so there is no quality loss
Make sure you do View -> Full Screen and not just maximize the SWF

    There are multiple ways to achieve this effect and I didn’t have the time to clean up my desktop to avoid privacy risks so i posted no source.
