Morph is one of the most powerful animation/motion tools in PowerPoint. Most instances of morph I see leverage Morph for simple movement of content. Here is an example from one of the TLC Creative design team where morph is used for elements that make up each slides background styling and provide movement within the presentation that is not directly moving top level content. 


There are 5 slides in this demo, and no on-slide animation, just Morph transitions.

As with all Morph effects, all content must be at the slide level. Content on Master layouts cannot be a part of the morph effect. And Morph relies on content being on the slides before and after the current slide (red arrows show images from slide 1 and where they go on slide 2. Yellow star is content end position from previous slide. Green stars are content start position for next slide).
