Kick Ass is a JavaScript bookmarklet which when clicked on, allows you to blow up a website in Asteroids-style fashion. This of course is just all fun and games, hit esc. or click anywhere on the screen, hit F5 and the website will reset back to normal.

Go here and drag Kick Ass to your bookmarks bar for easy access. Then, go to a website you feel like apocalyptically destroying, click on the Kick Ass bookmark, and a triangle shaped “ship” will appear on your screen. Use the arrow keys to move around, and the spacebar to fire ASCII projectiles at unsuspecting navigation bars and contact forms.

Happy hunting.
