Motion Path animations determine the route (path) and the direction in which the animated slide object moves across or around the slide. For example, you can move the slide object up, down, right, or left, on a preset or created motion path.
This sample presentation shows all Motion Path animation types available in PowerPoint 2002, 2003, and 2007 for Windows. This is not the actual PowerPoint presentation, it's an online presentation converted from PowerPoint to Flash by authorSTREAM. authorSTREAM does an awesome job of the actual conversion, but it still results in what we would call 95% fidelity. Few effects do not translate as they appear in the original PowerPoint presentation.
