From the SciVerse description:
The Author Wordle™ application lets you create a Wordle word cloud out of the titles of the last 100 papers from any author in Scopus.
Wordle is a toy for generating word clouds from text. The clouds give greater prominence to words that appear more frequently in the source text. Clouds can be tweaked with different fonts, layouts, and color schemes. The images created 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. Authors can use these Wordle word clouds on their own website as a representation of their research, or just for fun.
Can’t say I am a big fan of word clouds but a lot of people find them quite useful. See how it works for you in evaluating recent work by a particular author.
