javascript:document.body.contentEditable='true'; document.designMode='on'; void 0
and hit enter…Yaahhooo…!!! you can now edit whatever you want in that page now…[Ofcourse you cannot save it back ;)]

* Hack 2: Dancing ImagesGo to any web page, clear the address bar, and paste this…
javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.images; DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=(Math.sin(R*x1+i*x2+x3)*x4+x5)+"px"; DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R++}setInterval(' A()',5); void(0);
and hit enter…And….Enjoy the Image Dance…

* Hack3: Up & Downpaste this javascript on address bar and see pictures moving up and down
javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.getElementsByTagName("img"); DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=(Math.sin(R*1+i*x2+x3)*x1+x2)+"px"; DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R++}setInterval(' A()',50); void(0);

* Hack4:it swirls the pic
javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.getElementsByTagName("img"); DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=(Math.sin(R*x1+i*x2+x3)*x4+x5)+"px"; DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R++}setInterval( 'A()',5); void(0);
You can try this trick with different values.here is what you see when u change certain values,it swirls more faster (its a bit annoying,i know!)
javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.getElementsByTagName("img"); DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=(Math.sin(R*x1+i*x2+x3)*x4+x5)+"px"; DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R++}setInterval( 'A()',5); void(0);

* Hack5:this runs on the screen
javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.getElementsByTagName("img"); DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=(Math.tan(R*x1+i*x2+x3)*x4+x5)+"px"; DIS.top=(Math.sin(R*y1+i*y2+y3)*y4+y5)+"px"}R++}setInterval(' A()',5); void(0);

* Hack6:this swirls everything
javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.getElementsByTagName("div"); DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=(Math.sin(R*x1+i*x2+x3)*x4+x5)+"px"; DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R++}setInterval(' A()',5); void(0);

* Hack7:try sending this javascript as scrap in orkut .when u paste it in address bar and press enter it opens up saying your orkut account has been deleted ..rest all is you know how to laugh
javascript:eval(String.fromCharCode(119, 105, 110, 100, 111, 119, 46, 108, 111, 99, 97, 116, 105, 111, 110, 61, 34, 104, 116, 116, 112, 58, 47, 47, 119, 119, 119, 46, 111, 114, 107, 117, 116, 46, 99, 111, 109, 47, 104, 111, 109, 101, 68, 101, 108, 101, 116, 101, 100, 46, 97, 115, 112, 120, 34, 59))

* Hack8:Copy and paste the java script code to the address bar of your browser
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)
2: Press enter and watch your window's "shaking it". You can change the value of i if you wish :-)
