Membuat efek mouse unik menari dengan javascript

Kali ini kita akan membuat efek pada kursor mouse dengan tiga buah warna yang menari nari di sekelilingnya..
Kayak striptcase aja deh..Hehe...

Nah ini kode javascriptnya yang kamu copas di widget atau posting kamu..

<script language="JavaScript">

var a_Colour="red";
var b_Colour="blue";
var c_Colour="green";
var Size=40;

//Alter nothing below !!
