7. Unclosable Window

Yeah, you should recheck your mind carefully before run this script, maybe it will not be funny; and you have to enable popup for this damn script, lol.

<title>Unclosable Window</title>

<meta name="copyright" content="" />
<script language=JavaScript>

activ = window.setInterval("Farbe()",100);
i = 0, farbe = 1;
function Farbe() {

if(farbe==1) {
document.bgColor="FFFF00"; farbe=2; }
else {
document.bgColor="FF0000"; farbe=1; }
i = i + 1;

//if you don't want to freeze the browser uncommend the next two lines
//if(i >= 50)

function erneut(){,'');
window.onload = erneut;
<h1>Unclosable Window</h1>

8. Shaking the browser window for a while

Change the dimension of your browser window to Normal mode, maybe a half of the screen resolution is best; then run the code below by pasting it into the address bar and codessing the Enter key.
javascript:function Shw(n) {if (self.moveBy) {for (i = 35; i > 0; i--) {for (j = n; j > 0; j--) {self.moveBy(1,i);self.moveBy(i,0);self.moveBy(0,-i);self.moveBy(-i,0); } } }} Shw(6)
