These flash animations are "interactive", which means they do something cool if you (or your visitors) use your mouse to place the cursor over them. Sure they don't do much of anything else, but they look good! Just use the link at the bottom of the page to download all of these animations at once. If these aren't what you're looking for, head back to the animation gateway page for more flash animations. If you want to learn how to make animations like these yourself, check out the make your own animation page.
