In order for this simple graphic to be tough on your computer, you will need to adjust the alpha. do this by selecting the graphic on your main movie field, and on the menu, select Modify> Instance. This will bring up the "Instance Properties box. Select the Color Effect tab, and in the drop down box, select alpha. Adjust the alpha slide bar to about 80% or so, and click OK
Click on the 25th keyframe of the cruuent animation layer, and add a keyframe.
On the 25th keyframe, move the graphic image to another part of the movie field. adjust the alpha again, this time to about 40%.
Now, select any frame in between the 6th, and the 25th, and on the menu select Insert> Create Motion Tween.
Select frame 6 of the next animation layer, and drag the same graphic clip on to the field, or if you wish, you can make a new one. Then repeat steps 1-5 untill you have all of your animation layers have animations in them. You may want to change some of the alpha values, tint's, rotation, or even use shape tweening to make you animation more interesting.
This is how my example looks at this stage:
You may want to save again, before we get started with the actionscript.
