In my opinion just some paraphrasing of the old Sun documentation from several years ago. You're better to read the source material to fully understand what's happening in the VM, its a bit incomprehensible at first but a couple of reads and it really sinks in.
I am the author. I absolutely see what you're saying about the panning and zooming but do consider that the presentation was meant to be presented live and talked during. So each focal point would be on the screen for a few minutes while we talked about it. So if you're just sitting and flipping through them, I can see how it would be nauseating.
Also, I have to admit, it was an excuse to use Prezi which I think is really cool. I may have gone overboard with it, but its a lot of fun. It did seem to work pretty well live where the zooming out brought context to each topic by showing you the broader topic once in a while.
This just doesn't seem like the sort of presentation you should use Prezi for, that's all. The zooming and swooshing and panning and spinning and turning and ... distracts from what I care about: the content. Don't get me wrong, Prezi can be really cool in the right situation, just not this one.
Of course, distracting people from the content is exactly what I'm doing here, so I'll leave it at that :-)
