Twitterbar was a free twitter signature generator which you can place on your blog, emails or online forums. The signature displays your latest twitter message along with your twitter name in an image format, and generates the links for you.
This was something I made up for use in online forums, after finding free online tools at the time were pretty poor.
Unfortunately due to API changes by Twitter a few years ago requiring OAuth authentication, Twitterbar no longer functions and I have discontinued development.
