An article found on Flowing Data shows 17 visualizations created using Twitter. I personally like the visual style and interaction of TweetPad, but it’s a shame there is no online application. In order to use it one must download an application. I found Twitterfountain to be interesting and quite easy to use. Combining Flickr and Twitter can create appealing visualizations. The simplicity allows the user to try out a lot of combinations of images and tweets.
