Here's a fun website I found a while back called tagxedo where you can put in a link, twitter ID, word, etc. and it creates a fun picture for you! I could play with this all day with different ideas :) Tagxedo also has a shop where you can turn your creations into t-shirts, bags, coffee mugs, etc. Sounds like fun to me!
Here are a few of my creations!
