Hey Anthony I've just discovered that feedburner allows you to create custom images using your RSS feed titles. Under Publicize there is a service called Headline Animator. It automatically pulls in your 5 latest items and it's quite flexible about the placing of text within your image. I am working on my own sig at the moment, so far I've come up with this.
could be something to look into. The only problem for Economical Gamer is that you might have to change your article titles to make it useful.
edit: using your own banner I have created this as a sample (still using my own feed). Please excuse the rough job of editing out your previous text.
