I've been looking for some time now and can't find good alternatives to Turn.js. Turn.js seems fine, but I'd like to see some alternatives before spending the cash. If there is opensource alternatives that would be even better.
The main features I'm looking for are:
If you're okay with flash check FlashPageFlip, there's a free version available to commercial projects, it feels pretty fast and supports zoom.
There's also WowBook a paid jQuery plugin that's pretty nice.
