EarthquakeX has been discontinued
Email me when discounted: 
EarthquakeX is a port of an old prank/joke control panel for System 7 called Earthquake. When installed, your Mac will experience random earthquakes. This version is a bit different from the old one, but the principal is still the same. Ideally, you should install this on the computer of someone who is smaller and weaker than you.

If you wish to quit EarthquakeX, simply open up a Terminal window and type:

killall QUIT "Earthquake"

Even though I was expecting it, it still made me worry for my health for a second.

The only problem is that the screen is pretty much static when it's shaking. If you type, you won't actually see the letters until the shaking stops. I guess Earthquake just takes a snapshot of the screen and displays that in a full-screen window, so there's probably nothing the developer can do without doing some really advanced hacking. Oh well. It still gets the job done. (The job being to make the user a little bit nauseous.)

Excellent prank. I changed the application name, gave it a custom icon and sent it to a friend who fell for it. Pity he discovered which process it was so fast and killed it :P Perhaps you should give the process a more inocuous name :) BTW, Earthquake only shakes one of my dual 17" apple pro studio monitors.
