Twitsig is one of those applications. It creates a dynamic image that is displaying your user icon and your last message in a signature image. This signature can be embedded into forums or blogs for instance where signatures are allowed.

The process is simple. Just enter the twitter user name and click on the Get Code button. Three different types of links are displayed once the code is generated. One direct link to the image which does not get updated, one html link to embed into websites and blogs and one in BBcode for forums.

Since I do not have a Twitter account I have used the one from Bill Gates which means that you get his updated Twitter notifications in this article.
