Want to play a trick on your work colleagues? Then take over their computer with this joke USB device. Simply plug the innocent looking USB Prankster into your victim's computer and it'll take over and make random mouse movements, turns caps lock on and off, type out random garbage text and phrases and generally be super annoying. Handily, the Prankster features a time delay setting, so that after installing it, you can make your getaway safely before it starts misbehaving. The Prankster is highly annoying, but it'll never activate the 'enter' key or close or save documents, so it's mostly mischievous, not super-dangerous. However, it probably shouldn't be used on computers that control nuclear reactors, security systems for genetically recreated dinosaur parks and/or zombie experimentation units, captured alien spacecraft or freezers packed with delicious ice cream.
