This is a quick test to show basic classroom "viewbook" examples.  The two examples were chosen to show two different types of classrooms.  A real viewbook would likely be organized according to some descriptive parameters such as type of seating (e.g., fixed tables, moveable tables and chairs, individual sidearm desks), type of instruction (e.g., conventional lecture, active learning groups, TEAL, parliamentary discussion, computer), and probably special features (e.g., dual projection, high quality audio, hybrid/online support), etc.
