Visual Thesaurus
The creators of the Visual Thesaurus describe it as "an online dictionary and thesaurus of over 145,000 words that you explore using an interactive map". Like any thesaurus, it's great for tracking down an elusive word you can't quite recall, or simply browsing to improve your vocabulary. However, the added visual dimension of clicking on a word, and watching a cluster of related words (which are in turn clickable, and so on) rearrange themselves around your new selection, is wonderfully engaging and lends an appropriately organic feel to the whole process. See what you think!
