Blob space Graphic Effect

Colorful Polkadot Animated is pretty cute blog effect. Namely the colorful dots and movements such as resonance.

Here's the script

<script type="text/javascript">
// <![CDATA[
var colsel=new Array('#edf', '#dbf', '#c9f', '#b7f', '#a5f', '#93f'); // colours for animation - last colour is the 'background'
var speed=100; // speed of animation, lower is faster
