I love killing time on the internet. Which is why I had a blast with this: Worldle. With Wordle you can input any words you'd like, and they will be generated into a text cloud. Then you can change the arrangement, the colors, and the font, editing until you get a unique digital piece of art. You're given the option of importing del.icio.us tags, which is what I did.
I'm incredibly amused by how much a reflection of me this is.
