Many web browsers such as Firefox, Internet Explorer and Safari offer add ons through their respective sites that allow you to personalize and modify your browser.

Safari and here are some Plug Ins

One Add On that I have been very impressed with is Piclens. Piclens transforms your screen into a 3d wall of images. You can view the images from certain sites such as Google Images. It is also available for Safari. I think there is a lot of potential for this plug in. You could upload presentation slides to Flickr and use Piclens to view them as a slide show.

Thanks to Justin over at Medagogy for this tip. SearchMe Beta is a search engine with a different type of interface. It displays your results visually allowing you to flip through the pages.

You have the option to switch categories for your results at the top of the page. Otherwise, you can simply scroll through your web results using the bar at the bottom of the page. There is also a button at the bottom of the page that lets you toggle between the traditional text display of your results and the flip book style.
