Yes, I think you're right. What I'll probably end up doing is making some sort of grid template using the original spellbook as a guide before I make any of the graphics final, since this will help layout any of the spellbooks I decide to make. I will post the template once I get around to making it, so everyone else can use it.
I am probably going to do several animated spellbooks. I haven't seen many animated mods about.
BTW, not too familiar with that spell: Protection of the Cabbage!
