I entered my blog address. The site creates a "word picture" for you, and the size of the word is based on how often you use it. Apparently, I mention "time" a lot here; hmmmm, wonder what that means, Mr. Freud?
Anyhow, I am going to use it for vocab. words in my class. I figure for kids that are "eye-minded", it might be a cool, new way to look at things!
