Here is a link to the presentation. It's an SVG file best viewed in Firefox. Chrome seems to compress the images and not play the video on one of the first slides.
Now I'm not sure about how Prezi goes about its editing, but I'm really impressed with Jessy Ink. It works on the basis of each layer being a slide. You can assign transitions to each slide, and also to individual components on the slide (ala a typical presentation application). The bit that I wanted was the "Views" where each slide can have sub-views. It provides a way to conceptualise each slide as a giant poster, where you can navigate around that poster to highlight certain aspects of your "poster".
