Note: Try the below scripts on your own risk. As far as I know, these are not at all harmful. However, I will not be responsible for any damage.
Try these funny scripts just by copying and pasting in your browser’s address bar. Try demo links, in case the scripts are not working in your browser’s address bar.


Just paste the JavaScript below into the address bar of any browser then press Enter, it makes all pictures on the current web page fly around like a snake when you move the pointer.javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; var 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++}tag=setInterval('A()',5 );document.onmousedown=function(){clearInterval(tag);for(i=0; i<DIL; i++){DI[i].style.position="static";}}; void(0)
In the above JavaScript, you can change
document.getElementsByTagName("img")to any HTML tag that you want to apply.
Here’s some another versions of this effect: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;DIS.top=Math.cos(R*y1+ i*y2+y3)* y4+y5;} R++;}setInterval('A()',5);void(0);
Transform the web page into the eaditable mode
Transform the web page into the eaditable mode
javascript:document.body.contentEditable='true'; document.designMode='on'; void 0 This JavaScript code lets you modify any web page in real-time; and with Firefox, you can even save the modified web pages to your computer. You can do many funny things with the simple JavaScript above, such as: faking the screen capture of some proof, faking some hot news for April Fool’s Day… quickly.
