With the help of a neat little applet created by 18-year-old Swede Erik Rothoff Andersson, you can now treat any webpage as if it were the seminal arcade space shooter, Asteroids.  Just go to Erik's site - erkie.github.com, click or drag the button, and you're off and running.  W for thrust, A & D to turn, and Space to shoot!

Like Erik says, it's great for blasting a path through annoying banner ads! :D
