So, here's what I did to kick it off.
1. I created a new composition and sized it at 640 x 480 with a frame rate of 12 frames per second. (The 12 FPS was the optimal setting for the amount of data involved in this project. Nothing else would play correctly in my browser. However, for smaller animations, you can get a much higher frame rate for smoother animations.) I then created a simple background just by using the paint bucket tool.
2. I knew how long I wanted this composition to be. So I stretched out the Composition timeline to 24 seconds, then reset the timeline back to frame 0. I also knew I wanted the composition to loop, so I clicked on the word "Composition" in the Composition Timeline window, went up to the Timeline menu and selected "Loop." That's pretty simple.

1. After I created each text object, I clicked on them in the Timeline window and went up to the Timeline menu to convert them into Time-Independent Groups. This provides more flexibility than simple selecting "Time Independent."
