The Visual Thesaurus is a three dimensional thesaurus and dictionary with an intuitive interface that encourages exploration and learning. Available in both a Desktop Edition and an Online Edition, the Visual Thesaurus is a marvelous way to improve your vocabulary and your understanding of the English language. You have to see it !!! It is an outstanding application. Larry Blackmer showed me this and I have been an evangelist for this program every since. I love it and use it all the time.
