Progress on Procedural Animation

I am planning to use a procedural animation to make the Pop-up Book transition for the "festival of extroversion" in which the clymax and reaolution take place.
This is my latest project from 7104. It is a "Booknado". I do not plan to use the tornado form in the scene, but the procedural animation concepts will be used to make the book open and add to the cheerful/charming aesthetic I am looking to achieve for the intro to the scene.
Trying to figure out this procedural animation stuff... It is rough... Instead of just taking a simple cube or a sphere, and sculpting it into what you want, you have to manipulate things with nodes and code... e.g. the parameters of the books in the Booknado are manipulated with algorithms; the pages bulge out as the books opens, and it is adjustable and randomizable (in theory, it isn't working yet), and the formula that tells them how much to bulge is ((ch("../Rotation_Pivot/rz") /90) - 1 *-1) * (.6 - (0.06*(ch("../Stiffy/scale"))))

When I get it to work, each book will be different, with randomly assigned length, height, number of pages, the thickness of the pages (Stiffy in the above formula), color, thickness of the cover, and the speed of the flapping will be controlled by how fast it is going... In theory, but I cannot get the particle generator that is spitting out the points to assign a unique value to each book, so the random is not working.
