Earthquake is the typical, simple and small joke to spend on all your friends, which simulates an earthquake explodes inside the computer, moving all the windows abruptly.
The only downside of Earthquake is that the effect is reduced only to the visual field; that is, there is no sound accompaniment, which would have contributed much more realism to this joke. Even so, it is a tangle to hang out and make friends laugh.
To cancel the earthquake, you just have to press the ctrl + Alt + Del keys, and it is advisable to do so after a while it is unbearable to see all the windows moving so sharply.
