Is it art? Is it a visual summary of a piece of writing? Is it a cool web play toy?
Yes!
It's all of these things, and regardless of how you see it, I believe Wordle has merit and is worthy of my recommendation. Wordle.net is a website that allows you to create something like what you see above from a piece of text. It takes the words from your text (the one of above is from my other post today) and creates this cloud of words. The words used most in the text appear larger.
You have a variety of ways to change your visual creation, including colors, shapes and a vertical or horizontal orientation. You will find samples on the Wordle homepage, and you can view many more in the site's gallery.
Check it out and give it a try. If you come up with a creative use for Wordle, let me know!
