2.Optical Mouse Prank - Only a few of us still use the computer mouse with a rolling ball in it, so this is an update for the optical sensor mice. Simply stick a piece of tape on the laser sensor in the bottom, color the nonstick side and watch the victim get frustrated as the mouse goes haywire.
3. Screenshot as Wallpaper Prank - this one deserves a little effort, but the reactions make it worthwhile.
Simply take a screenshot of your friends computer with printscreen, hide all the icons, minimize open applications, and set the taskbar on auto hide. Watch their reactions as they attempt to select any icon or application without getting any response.
4. Rotate Screen Prank - this one works on most Intel computers and is very easy to see if it does. Simply press ctrl + alt + arrow direction preferred (up, down, left, right). Afterwards, leave the computer and watch, for the victim cannot bring it back unless he knows the magic formula.
5. Transparent Desktop Prank - You just take a shot of what’s behind your screen and make it your desktop background. And yes, I’ve tried it, and yes, it’s more difficult than it looks to get it just right, especially if you don’t have a laptop. It’s all about the fold-down screen.
