EarthquakeX 1.1 (Mac)
Source: John Schilling
EarthquakeX is a port of an old prank/joke control panel for System 7 called Earthquake. When installed, your Macintosh will experience random earthquakes. This version is a bit different from the old one, but the principal is still the same. The old version, being a control panel, allowed you to set the quake frequency, duration and richter level. This version acts more like an extension; user control over the quaking is not allowed (read tip below, however). Ideally, you should install this on the computer of someone who is smaller and weaker than you. Then simply double click the EarthquakeX icon. It's a faceless background app, so it will look as if nothing has happened. After a few seconds, your Mac should experience a tremor. If you wish to quit EarthquakeX, simply open up a Terminal window and type: killall QUIT "Earthquake" If that doesn't work, simply choose "Log Out" from the Apple menu, then log back in.
