You know, the electronic files where you can view info and photos in a virtual book? Where you can go from one page to another by clicking on the page corner and it will "flip" with a 3D effect? I want to know how to do this. The research I've done points to a lot of web services that you pay to convert documents you upload to their site, but no actual software packages one can buy. Can anyone offer some advice on where to find applications that I can generate these flip books? Thanks.
