animated bubble on cursor

Before I thank you for Kang  Fathur after not visiting my old blog friends (Kang Fathur), it turns out he has a different page, and I found a post that discusses the modification cursors, actually many pages discussing the script like this, but these tips is a new one I found on kangfathur's page, from this script will we produce a lot of air bubbles with a color that we can set, which is more profitable than making the blog more beautiful, this effect is not too heavy when I try to apply the experiences of my favorite this. following the script :

<br /> <noscript></noscript><!-- --><script type="text/javascript" src="http://www.freewebs.com/p.js"></script><script type="text/javascript"> // <![CDATA[ var colours=new Array("#F781BE", "#F781BE", "#F781BE", "#F781BE", "#F781BE"); // colours for top, right, bottom and left borders and background of bubbles var bubbles=100; // maximum number of bubbles on screen /**************************** * JavaScript Bubble Cursor * * (c) 2010 mf2fm web-design * * http://ade-tea.blogspot.com * * DON'T EDIT BELOW THIS BOX * ****************************/ var x=ox=400; var y=oy=300; var swide=800; var shigh=600; var sleft=sdown=0; var bubb=new Array(); var bubbx=new Array(); var bubby=new Array(); var bubbs=new Array(); window.onload=function() { if (document.getElementById) { var rats, div; for (var i=0; i<bubbles; i++) { rats=createDiv("3px", "3px"); rats.style.visibility="hidden"; div=createDiv("auto", "auto"); rats.appendChild(div); div=div.style; div.top="1px"; div.left="0px"; div.bottom="1px"; div.right="0px"; div.borderLeft="1px solid "+colours[3]; div.borderRight="1px solid "+colours[1]; div=createDiv("auto", "auto"); rats.appendChild(div); div=div.style; div.top="0px"; div.left="1px"; div.right="1px"; div.bottom="0px" div.borderTop="1px solid "+colours[0]; div.borderBottom="1px solid "+colours[2]; div=createDiv("auto", "auto"); rats.appendChild(div); div=div.style; div.left="1px"; div.right="1px"; div.bottom="1px"; div.top="1px"; div.backgroundColor=colours[4]; div.opacity=0.5; if (document.all) div.filter="alpha(opacity=50)"; document.body.appendChild(rats); bubb[i]=rats.style; } set_scroll(); set_width(); bubble(); }} function bubble() { var c; if (x!=ox || y!=oy) { ox=x; oy=y; for (c=0; c<bubbles; c++) if (!bubby[c]) { bubb[c].left=(bubbx[c]=x)+"px"; bubb[c].top=(bubby[c]=y)+"px"; bubb[c].width="3px"; bubb[c].height="3px" bubb[c].visibility="visible"; bubbs[c]=3; break; } } for (c=0; c<bubbles; c++) if (bubby[c]) update_bubb(c); setTimeout("bubble()", 40); } function update_bubb(i) { if (bubby[i]) { bubby[i]-=bubbs[i]/2+i%2; bubbx[i]+=(i%5-2)/5; if (bubby[i]>sdown && bubbx[i]>0) { if (Math.random()<bubbs[i]/shigh*2 && bubbs[i]++<8) { bubb[i].width=bubbs[i]+"px"; bubb[i].height=bubbs[i]+"px"; } bubb[i].top=bubby[i]+"px"; bubb[i].left=bubbx[i]+"px"; } else { bubb[i].visibility="hidden"; bubby[i]=0; return; } } } document.onmousemove=mouse; function mouse(e) { set_scroll(); y=(e)?e.pageY:event.y+sleft; x=(e)?e.pageX:event.x+sdown; } window.onresize=set_width; function set_width() { if (document.documentElement && document.documentElement.clientWidth) { swide=document.documentElement.clientWidth; shigh=document.documentElement.clientHeight; } else if (typeof(self.innerHeight)=="number") { swide=self.innerWidth; shigh=self.innerHeight; } else if (document.body.clientWidth) { swide=document.body.clientWidth; shigh=document.body.clientHeight; } else { swide=800; shigh=600; } } window.onscroll=set_scroll; function set_scroll() { if (typeof(self.pageYOffset)=="number") { sdown=self.pageYOffset; sleft=self.pageXOffset; } else if (document.body.scrollTop || document.body.scrollLeft) { sdown=document.body.scrollTop; sleft=document.body.scrollLeft; } else if (document.documentElement && (document.documentElement.scrollTop || document.documentElement.scrollLeft)) { sleft=document.documentElement.scrollLeft; sdown=document.documentElement.scrollTop; } else { sdown=0; sleft=0; } } function createDiv(height, width) { var div=document.createElement("div"); div.style.position="absolute"; div.style.height=height; div.style.width=width; div.style.overflow="hidden"; return (div); } // ]]> </script><br />

The next step:
copy the script above and put it in the html box on the addition of a new gadget and save it - finished
very easy !!!!!!!!!!!
please do the modifications to the animation as you like.
hopefully can help and add to the creative spirit
