David,
I have looked at this page and a few others. I was intrigued by your tagxedos. I load the program but can't find out how to create. It looks interesting but unavailable. Also it seems you need the progrma to view the animated word cloud so a word to the reader might be needed.
Hi Jack,
Thanks for this. Are you using Safari? I think the animated cloud uses Microsoft Silverlight. I should work on Safari, but you are absolutely right it needs a note to invite users to install Silverlight.
It will work on IE, Firefox, Safari4+ Chrome.
Thanks
