Endless loops are not always useful, sometimes you need something to move once and then stay put and be available in the new location on subsequent slides.... You may have noticed that the last property cannot be achieved using motion-paths by themselves. If you duplicate a slide with moving objects then on the new slide the objects are in their initial rather than their final positions.
The solution to this problem actually makes motion-path animation easier to keep track of. First, duplicate the object that you want to move and relocate the duplicate to the final position. Add the motion-path to the first instance of the object and follow it with a "Disappear" exit event. Add an "Appear" event to the duplicate and make that occur simultaneously with the "Disappear" of the original object.The effect of these three events is a smooth move to a new location that finishes with a copy of the object in the new position that may be carried forward to a new slide. Another bonus to this technique is that the motion-path doesn't have to be perfect. Provided that it moves the object reasonably close to the new position then the eye will automatically fill in any gaps when the sequence is run.
Reasonably stepwise instructions on how create a move-and-replace animation.
Shown below is an animation intended to show how students identify key words and use them to build "Learning Objectives"
The "key" words from the text on the right were copied into individual text boxes so that the "Motion Path" "Lines" could be added to each.
"Lines" is a two point straight line motion path. Click on the path and an image of the moved object (text, in this case) appears to make it really easy to move the endpoint of the motion path to the right place (This is a new innovation in powerPoint 2013, it used to be a lot harder to guess where to put the endpoint of the motion path)
If that was the end of the argument then the motion path is all that would be required....but sometimes, moving the text is only the start of a sequence.....
To create the illusion of moved text that will persist on to the next slide
This is easier to see on the powerPoint download than it is to explain, but move/disappear followed by appear is actually the simplest way of moving any object precisely to a new location, because it it easier to place a text box exactly where you want it to be than it is to determine the endpoint of the motion path. Provided that the two are reasonably close together, the eye doesn't notice the discrepancy (unless you are really looking for it)
The point of this animation is to highlight "key words" in a fragment of a PBL scenario and show how these word may be fitted to the "medical model" of disease to create a learning objective that encourages systematic investigation of the condition. This sequence was followed on a subsequent slide with a comparison between an "ideal" learning objective and actual student generated learning objectives.
These sort of movements are also fun when they all occur at the same time..... click through to see that effect
The same technique may be used to rearrange elements in a list. Shown here doing exactly, changing list order from by alphabet to by popularity.

Another variation on a theme where the elements of a lecture covered so far are ticked off (made to vanish), leaving only what still remains, which is then moved to prominance.
This demonstration may be downloaded here.
The last two animations are more about style than substance. Of themselves they add very little additional information to the presentation. BUT style can be important.... How better to reinforce the concept of a rearanged list than to show the list rearranging...
