Making the internet a better place, one bookmarklet at a time.
So bookmarklets are all the rage these days. There can be some pretty useful ones like Readability, which strips non-useful information from any webpage, leaving you with nice easy to read text. There are of course the less useful ones, such as Cornify, which covers any webpage with unicorns and rainbows.
Over lunch today, I (with a lot of help from Brent (thanks Brent!)) created Papmic Sansrus. Papmic Sansrus has the ability to make any webpage the most offensive webpage in the world... but only if you are a designer. It will replace the font of every word to an alternating combination of Comic Sans and Papyrus.

Click here to see Papmic Sansrus in action, or drag the link to your bookmarks bar for easy use on any website. (If you are reading this in a feed reader, you might need to visit my actual website to witness the glory.)
My original intent was to alternate fonts between every letter, but for simplicity's sake, I decided to make a lite version that limits it to every word instead. Through a happy mistake, however, we got it working the way I originally wanted. Click here to see the ultra version, though you might want to refresh the page if you're reading this with the lite version active. This ultra version works well in Firefox, Chrome and Safari, but has some trouble in Internet Explorer. It also might break some page layouts slightly, but I feel it only adds to the effect. It will also cause your browser to chug/crash if you try it on a very text-heavy site.
Brent is also the author of another fun bookmarklet called 3D. Using this without 3D glasses will probably induce headaches. A couple more hideous ones I've found add drop shadows to everything, or add drop shadows to just text. I am unaware of the author of these gems.
Combine Papmic Sansrus with 3D for the ultimate web experience.
