OMFG csn, I wouldn't be at all surprised if someone did it now.
I remember back in the day, there was this guy who made silly animations on it, and one of them was an animation of a "demo" given at a user's group meeting. It had a window with A icon (a big letter A for an icon) and a new application. There these series of applications called virus-x, screen-x etc... written by the same bloke. virus-x was a pretty good anti-virus program, and screen-x would let you run multiple desktops (we're talking 1989 or so here, long time ago).
One of the "fake" applications in this animation was one called "keyboard-x" that randomly remapped all the keys on your keyboard every 30 seconds.
You can guess what the author of virus-x and screen-x wrote a few weeks later...
