I have been looking at prezi (http://prezi.com/). There's lots of aspects there that don't appeal to me, but I find the general idea very nice: a presentation is sort of a big poster, with some background graphics. You define areas on this poster into which your content goes (so these would be the "slides" in a conventional presentation). When you show your presentation, your viewer will zoom in on these areas and present them full screen, and it will move along a predefined path, thus showing the areas (slides) in a certain order. The nice thing is that you can, at any moment, zoom out and show the entire poster, thus giving an overview of your presentation in which only the bigger elements (headlines etc.) will be readable. Now I was wondering if the same couldn't be done with ConTeXt, pdf and javascript: producing a big pdf with a background image would be fairly easy (metapost's vector graphics would look good at any zoom level). Placing slides with content there could be done via layers. Zooming in and showing certain areas is doable (but obviously would depend on the pdf viewer, especially for the full screen mode). I have no idea if we have support for rotating areas in a pdf viewer. Would javascript be capable of automating this, i.e. defining areas in a pdf, displaying them at a certain zoom level, and move from one area to the next? I think this would be a nice alternative to traditional slide shows.
