I found the coolest thing yesterday. It’s a website at http://wordle.net/ I entered text, and a program made a picture out of the words I used. The more times a word appeared in the text, the larger that word appeared in the picture. And… it’s free.
I used text from a blurb I wrote about my manuscript. It’s the sort of the thing that might appear on the inside cover flap of a book. Wordle made an interesting image out of my story.
