Wordle Image
I have found an interesting visual tool called Wordle. It can be accessed through wordle.net. It will take a text and highlight the most frequently used words by making them the largest words of the display. The view you see here is from the text of an article which I wrote for the Evangelical Review of Theology in the January 2007 edition. The article is entitled "Prayer Revivals and the Third Great Awakening."
