>My laptop came with a driver that intercepts my keystrokes and sends signals to the keyboard so that it can light up the LEDs under the keys I pressed. What caused an insane design like this to even come into existence is beyond me, no doubt it came down to saving a few cents in manufacturing. I replaced this functionality with free software and I'm not sure if I even want to know whether there are any vulnerabilities in that driver. That sounds pretty cool and hackable actually.
