Take any bookmarklet code. For this example, I will be using Evernote (for other bookmarklets don't seem to work.. for example, ones for ReadItLater. You can find the bookmarklet here. "http/evernote.com/about/download/"

Or the javascript code itself

javascriptfunction(){EN_CLIP_HOST='http/www.evernote.com';try{var%20x=document.createElement('SCRIPT');x.type='text/javascript';x.src=EN_CLIP_HOST+'/public/bookmarkClipper.js?'+(new%20Date().getTime()/100000);document.getElementsByTagName('head')[0].appendChild(x);}catch(e){location.href=EN_CLIP_HOST+'/clip.action?url='+encodeURIComponent(location.href)+'&title='+encodeURIComponent(document.title);}})();

Copy and paste into the URL window. And watch as the  blue bar bouncing begins!
