A number of presentation add-ins supply presentation templates, but VisualBee is a bit different. It lets you enhance an existing presentation. When you run VisualBee, it analyses the presentation's text and structure and tries to improve what you've done on your own. It doesn't get everything right, but it'll generate a few keepers -- and you can easily discard what you don't like. The bank of images alone is worth the download.
