A masterpiece for interactive PDF presentations.
I've been using FlipBuilder for a few years now, and this program is exceptionally well done. It's stable and feature-rich, and does far more than I initially planned for online PDF presentations. It's so flexible and capable that I'm inspired to use PDFs for many more projects than I ever imagined. It's a wonderful source of ideas and creative methods of interactive, multi-media presentation. And the support is fast, friendly, thoughtful, and thorough.
