A book at birds look

I always wanted to look at torn book in bird's view. So that you can view whole 1000-pages book
and zoom when needed. So made experiment with d3d11:

Stroustrup: The C++ Programming Language:

 Concrete mathematics by Knuth

The Art of Computer Programming (Volume3) Knuth
(this book is special, little margins do their thing - it looks just like a huge newspaper (3m x 15m))
