Google Experimental Search

Recently, Google has made available some "experimental" versions of their search engine. If you log in to Google and go to their Experiments section, you can join the experiment of your choice in order to get access to the new features.

For example, one experiment allows you to view search results in the context of other types of information-display, such as a timeline, on a map or with additional information (about a given topic) displayed.

Another mode involves keyword suggestions in the form of a drop-down autocomplete box, showing you realtime suggestions based on what you begin to type, sorted by preponderance of result.
