If you're as sick of Charlie Sheen stories as we are, then you'll love the new browser plug-in for Firefox and Chrome from the Free Art & Technology Lab, "Tinted Sheen", that literally blocks him out.
Once you install the app, anytime you browse to a page with the words "Charlie Sheen" they will be replaced by a black bar. Even the pictures of Sheen will get blacked out, saving you from further exposure to the insanity.
Now if they would just release a Lindsay Lohan version...
p.s. Yes, I recognize the irony of writing a story about Charlie Sheen that is about how tired I am of stories about Charlie Sheen.
