Hey, look what I made:
If you have a blog or anything else with an RSS feed, you can generate a "collage" of words found on that page at wordle.net. It's free and it's fun, and you can adjust the color and font and all kinds of things. (I used a color palette found at Kuler, my favorite artsy online time-waster..)
Note: you'll need to screen-capture it (I recommend the very swell SnagIt) if you want to post it on your blog as a full-size image. Blah. (Of course, you can use Print Screen too, but SnagIt is seriously better & easier to use.)
It's like making art, but without all the tedious messiness and trial & error...
