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. (from http://www.wordle.net/)
I like to save my wordles to my computer for future use. The how to video is one I made to show you how you can save your wordle creation as a jpeg file for using in other presentations.
