This is the coolest way to kill some time or to get rid of annoying ads:
Take your little spaceship and destroy every website you like - without any installation or signup. Give it a try!

This is really easy: Just drag the red button on the right side to your bookmark bar. Then go to any other website and click on your bookmarklet to activate the spaceship.
