Wordle is a site that’s making the blog-rounds. The site has a Java applet where you can put in a bunch of text (or your del.icio.us tags) and makes tag clouds out of them, with multiple font/color options. I made on of the headers on my site with it, and there are some really interesting ones on their site (you can save them to a gallery there). Here’s Barack Obama’s ‘Race Speech’ as interpreted by Wordle, for instance. Saw it at Lifehacker but it’s all over the place.
