I would like to write a web interface that resembles Prezi.com in its user experience. What would be the best technology for that purpose?
Project requirements:
My natural candidates are Flash and HTML5.
Prezi.com is an alternative platform for presentations that uses single canvas zoom/pan/rotate controls instead of classic slide-by-slide interface. An example is available here.
Edit
The visual part of my website needs to display multiple widgets (images, videos, text) on canvas and allow the user to navigate by zooming and panning. Each widget would have its own native zoom. The number of widgets would be enormous, however, simultaneously only a small number of widgets are visible.
If you need it fast I think you'd probably benefit from the whole application suite Adobe has to develop Flash-based applications.
Android Tablets should be able to run it, as well as all desktop Browsers. Only iOS (iPad and iPhone) would be left out.
IMHO HTML5 is not mature yet.
Alternatively, you could use Adobe AIR and compile for the web, iOS and Android natively.
