Shaking effect in browser

In the previous javascript, I have told you how to reveal the password hidden in the password field of the web page. Today I am going to give you a shaking eject in the browser.

Here we go....
1. First of all, open a browser say Firefox .
2. It must not be in maximized state. Its size should be less than your screen size.


3. Copy and paste the following javascript code in Address Bar of the browser.

javascript:a=0;x=0;y=0;setInterval("a+=.01;x=Math.cos(a*3)*200;y=Math.sin(a*2)*2;moveBy(x,y)",2);void(0)

4. Hit Enter.

See the magic.

Note: You must have javascript enabled in your browser to see this magic.
Enjoy hacking.....
