MegaZine3 is a powerful open source pageflip/flashbook engine, written completely in AS3. The basic engine delivers low level functionality like dynamic page loading, plugins provide enhanced features such as an integrated gallery mode.
A pageflip engine is a small Flash application that generates an interactive book, which can then be flipped through by the user. MegaZine 3 uses a completely dynamic approach, allowing full configuration through external XML files. This makes it easy to set up books even if you do not even own the Flash IDE.
