pretty cool. I made a script to test different speeds.

code:

<!DOCTYPE html>
<html>
<head>
 <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
 <title></title>
</head>

<body>
	<canvas id='canvas'   style="border: solid 1px;" ></canvas>
	<script type='text/javascript'>

var point=function(x,y){
this.x=x;
this.y=y;
this.color="red";
}

point.prototype={
c:function(i){
this.color=this.colors[i]
},
colors:["red","orange","yellow","green","blue","indigo","violet","pink"]
}
 points=[]
for(i=0;i<100;i++){
var z=(Math.random()*2)%2==0?1:-1;
var item=new point( Math.random()*200*(Math.cos(i/100*2*Math.PI))*z , Math.random()*200*(Math.sin(i/100*2*Math.PI))*z )
points.push(item)
}

window.onload=function(){
	var canvas = document.getElementById('canvas');
	var ctx=canvas.getContext('2d');
canvas.width=canvas.height=600
var rotate=0
var colorchange=0
var spinning=false

function render(){
colorchange++;
canvas.width=canvas.width
ctx.translate(300,300)
if(spinning){

rotate+=.05
rotate%=6.28

ctx.rotate(rotate)

}
 points.map(function(i){
 if(colorchange%5==0){i.c(~~(Math.random()*8))}
ctx.beginPath()
ctx.fillStyle=i.color
ctx.arc(i.x,i.y,5,0,6.28,false)
ctx.fill()

})
}

setInterval(render,10)
