If you are looking for a way to spice up a presentation try wordle. According to their website at www.wordle.net 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. You can save the Wordles to a public gallery and link to them. This application works better with a PC than a Mac. Here is one I created.
