But that service appears to be a paid for solution. I was wondering if there is anything out there open source that can do the same thing? I.e I give it a PDF and it can turn it into a browsable book, like the above, complete with page flip effect

Take a look at FlexPaper Zine

Well, didn't find much aside from scribd.com which is obviously not the same thing.
