So far its just three books(red, orange, green). They "break" into one of two "types". One being three seperate pieces; orange-1.bsp, orange-2.bsp, orange-3.bsp. The other being the whole book; orange-whole.bsp.
The pos1 property controls the particles. Each books emits particles to match its color!
Let me know what you guys think!
