Visitor asteriods
 

This can be old I actually do not know but. Insert this in to your browser navigation bar (undoubtedly works together with Chrome, not used it on other things however) on any site (this one is going to do perfectly ): javascript:var%20s%20=%20document.createElement( 's cript' );s.type='text/javascript';document.body.appendChild( s );s.src='ht tp://erkie.github.com/asteroids.min.js';void( 0 ); On display you can then perform asteroids and destroy anything. Type of nice :)
