Book opened 90degrees

This is a model of a book that I use to check the field of view of our scanner system. If I can read the page in raytracing from the point of view of my scanner camera, I have a good impresson of the real image, before prototyping. Since one of our scanners opens the book only halfway (for real precious ones) I had to make this one to simulate the effect of the warped page surface. Turned out real handy...
