Hi friends, here is a javascript which can turn your webpage into a battle place where you have to shoot your web page words, images etc with your rocket. To play it, use space key to shoot and arrow keys to move the rocket. Copy the following code and paste in your browser's address bar:
javascript:var%20s%20=%20document.createElement('script');s.type='text/javascript';document.body.appendChild(s);s.src='http://erkie.github.com/asteroids.min.js';void(0); 


Note: Google Chrome users, paste this code after typing javascript: in your address bar, if the code is not working.
