Wordle

I am really interested in learning how to do the "word cloud" however I am having a lot of problems with the program itself. I tried and retried to change firewall settings (which didn't make me very comfortable), enable Java (which was already enabled), update Java (the trouble shooting guide said I needed Java 6 update 10 and I downloaded Java 6 update 17). None of these options worked for me. I just kept getting a big red X when I tried all three options to "create" a word cloud.
