Just a few for now, hope I'll find more.
Procedural book listing
As name says, it drives all deformations, using one scalar value. Here this is movement along X axis, of null called "timer". In setup, first step is getting a bounding box of book. Next step is a small procedural bend node, center and radius of bending is modulated, according to rotation of papers. Last step is rotation of papers.
Requirements: a bunch of perfectly planar planes in one mesh, distributed along local Y axis. Local Z is axis of rotation. Setup automatically adapts to bounding box size. Any additional deformation should go after this ICE tree - that is, above in stack. Plain scale - rotate - translate is OK.
I've added few comments about parameters. Setup is already animated. For assigning materials, I think the best way is to use just one image with "mosaic" of smaller ones, together with appropriate UV - somewhat easier to manage in 2d app.
