The first is Searchme. This is a search engine with Oomph. It has a cool Mac like interface of flipping through searched web pages. You can preview pages, even read a little bit as text. The search engine is a little slow though. And it doesn't return the large number of results as say a Google does. But it sure has a great interface.
The second is even better. Addictomatic searches the best live sites on the web for the latest news, blog posts, videos and images. It's the perfect tool to keep up with the hottest topics, perform ego searches and feed your addiction for what's up and what's now. It presents the result in a great dashboard interface with different search results showing up in small windows of their own. I love this one.
Finally, searchCrystal lets you search and compare multiple engines in one place. It is a search visualization tool that enables you to compare, remix and share results from the best web, image, video, blog, tagging, news engines, Flickr images or RSS feeds. It visualizes the overlap between search results and places the most relevant items close to the display’s center. You can even embed searchCrystal as a Widget on your site or blog to share personalized crystals. Take the searchCrystal Analytics Toolbook for more info.
