If you are in need of royalty free professional animations or graphics you should check out Digital Juice. I have several of their products and use them in almost every production. These guys have some great stuff available and are constantly cranking out new volumes. All products have a preview online so you know exactly what you are getting before purchasing. They have a Digital Juice Showcase where you can see how others are using their products. This is a great place to get different ideas on how you can make your productions better! They have been running some insane specials lately so it might be a good time to start building up your library.
