Here are two sites that are great for the visual learner/thinker part of your brain:
Try out the search engine Quintera. Type in a search term and you get a cloud of related terms. Click on words in the cloud to narrow your search. You can search images the same way. Very cool.
Also cool is 10X10. This site collects the 100 most prevalent images and words appearing in online news outlets every hour—then arranges them into a collage. Click on the collage to enlarge it, and then roll your mouse over the list of terms to the right. Click on one of the terms and get the picture enlarged and links to the news stories.
