You absolutely have to watch this video about Microsoft's Photosynth if you want to understand what Mark Evans is talking about when he says that will be the way we can browse through an online newspaper in much the same manner we do a paper newspaper. (watch the video before reading more!)
However, I think that Photosynth will be much more than that. I think that it will probably revolutionize the way we do any of our online work. Done correctly, ordinary websites wouldn't require any clicking in order to navigate them. Users would simply zoom in and out, and I'm sure that it would even be able to add fields. One corner of a giant 'image' could be a users inbox, while another could be Wikipedia. There is a lot of possibility here.
I realize that a Photosynth-style web is probably still a long way off (as most computers probably don't have the processing power or connection speeds necessary to make it work) but we all know how quickly technology is changing.
I'm probably going to be dreaming about some sort of Photosynth-Facebook super-mashup tonight...
