is a web application for making presentations,
almost a Powerpoint replacement. It works by zooming in
and out, using scale as a hierarchy. It's free for limited
use, and costs a subscription for more advanced features.
They have been around since April 2009 or 2.5 years.
I don't know exactly which technologies they use, or if
any of this is patented. But I think this is a novelty in
web user interfaces, similar to the introduction of
Google Maps in February 2005.
I think that something similar to Prezi could be used for
presenting digitized books, but I'm not sure exactly how.
Have you seen any such examples? Please, let me know.
As a first example, I took some scanned book pages and
made this little demonstration in Swedish, which you
can step through just to get the feeling,
