Limitless Canvas as a way to design websites

I just came across this interesting technology that may be the future of web page design… if you are familiar with Prezi, the presentation software, you will probably concur that it's not much of a jump to see it as an incredible expandable web site navigation system without the need for coding… but its past dependance on Flash means that it has been restricted to laptop demo’s and such.
In researching Prezi I cam across a reference to Webpgr and it looks incredibly useful.. its just not quite clear how the responsive interface works and these days investing in a site that is not responsive is a no no.
