Play Asteroids with your web browser

Looking for something to do this lunchtime? Why not indulge your childish side by playing Asteroids online. But this is no ordinary Asteroids. Made by a GitHub this clever game allows you to shoot and destroy html elements on a webpage. All you have to do is visit his site and drag the big green box (that you can see on the screen grab) into your bookmarks bar. Then head over to any other site and click your link.

From here, a little rocket appears which you can move around your screen using the arrow keys. And, with a little press of the spacebar, you can destroy anything you want.

In my case I thought I'd remove Sheffield Wednesday off the BBC Sport site. But, that's just because I'm a Rotherham United Fan.

Happy playing.
