No cash in your pranking budget? No problem. Put a more organic edge on the phantom concept by messing with your cubicle mate’s mouse the old-fashioned way.
Plug an extra mouse into an open USB slot on the back of your buddy’s PC. If you have a wireless USB mouse, that’s even better. When your colleague sits down, casually move your secret controller around from time to time. Remember, subtlety’s the key.
The Final Product:
The jumping mouse pointer, if performed well, will be just enough to make your victim wonder if he’s seeing things — or if his computer has developed a mind of its own.
