This is a snapshot from a Processing sketch that demonstrates turning pages in a book.

This article was the inspiration for the sketch and although I did manage to program the math calculations, I did have some problems with managing transparency of the background so thanks to calsign and PhiL.ho for their help on that.

If you want to create your own books it is fairly easy to modify this sketch to use your own images. The instructions are in the main skecth file and you should not have to modify the Book.java and Page.java code.
