Click on the September archive and then click on comments to see all of the 2009 display blogs. I am going to start blogging with a "Title" and also put the post into the blog so it can be archived by month. Should have done that to begin with. If you are new to this world of "Animated Displays", I suggest you not only read mine, but other blogs. They will help you learn NOT to make the same mistakes others have.
