Wordle is a toy for generating “word clouds” from text that you provide. The clouds give greater prominence to words that appear more frequently in the source text. You can tweak your clouds with different fonts, layouts, and color schemes. The images you create with Wordle are yours to use however you like. You can print them out, or save them to the Wordle gallery to share with your friends.
I’m not sure yet what the possible uses of this visualization tool are beyond creating a whiz-bang slide in a presentation… I suspect that the limit in potential lies within me at the moment… the sample output shown on the Wordle site is fascinating. A stunning visual version of a tag cloud can really help focus where attention is directed…. the tool also allows you to cut and paste a random set of text and apply the same visualisation techniques.
