US$10 device.... https://www.thinkgeek.com/product/ae83/#tabs The Keystroker emulates a keyboard and mouse and periodically makes random = mouse movements, toggles caps-lock and types out odd garbage text and phras= es. Switches on the side allow you to choose between keyboard garbage typin= g, caps lock-toggle, annoying mouse movements or all three. An adjustment d= ial sets the duration between "events". The Phantom Keystroker never hits the return key and it never clicks the mo= use button. However you should not use it on anyone's system who is doing c= ritical work where disruption could cause serious consequences. The Phantom= Keystroker is a joke, like any joke you need to use prudence and judgement= when executing it. You have been warned!
