The new Devil Drive elevates the office prank to a new level of sophistication and maddening effectiveness. It looks like a regular USB thumb drive, but it's actually a devious device of electronic harassment. Its use should be strictly limited to deserving subjects only.

The Devil Drive has three functions: 1) it causes annoying random curser movements on the screen, (2) it types out random phrases and garbage text, and  (3) it toggles the Caps Lock. It allows you to select any combination of these frustrating functions, or all of them. It also allows you to set the time interval between events (ranges from 5 seconds to 15 minutes; the longer intervals are recommended for the most maddening effects). Note: the Caps Lock toggle function does not work on Macs. To deploy the Devil Drive, just discreetly insert it into any unused USB port on the victim's computer (no drivers are needed).

The Devil Drive never hits the "Enter" key and it never clicks the mouse button, but still you should not use it on anyone's computer who is doing critical work where any disruption could cause serious consequences; like any prank, exercise prudence and judgment before deploying.
