hehe javascript aint all complicated gadjet making or softwere making since you can have fun with it too
my first trick will let you edit webpages with java script ok first open your webbrowser if you have explorer i doubt this will work ...eithr way open your webbrowser and thn open a web page such as msn or wat ever then in the url bar or the adress bar or watever you call it paste this code
javascript: document.body.contentEditable = 'true'; document.designMode = 'on'; void 0

and press enter ok now you can edit any of the things in the webpage....for starting try highlaiting something and pressing backspace


for the second trick open tha web browser like i said before and then this time doo a google image search once the images all load in the url/adressbar paste this code and press enter

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);

this makes all images fly hehe fun eh..hope you have fun and please no negative cooments

NOTE:non of this is permenant so if yyou think of hacking nope cant do
