It takes quite a bit to impress me when it comes to software, but yesterday I was blown away by this little plug-in for web browser called PicLens. Think of it as a browser add-on that gives you something like the i-Tunes style cover flow visual browser but for web sites like YouTube and Flickr. The stunning thing is how fast and responsive it is — assuming your net connection is reasonably fast. This plugin only runs on Windows and Mac and only on IE, Firefox & Safari. Try it, it rocks.
