why "Glass Atlas"?

I wanted to write a book about the importance of proper beginning and ending theology - the alpha and omega of history. It would be a biblical "worldview", so the appropriate book-type would be an "atlas". I also wanted it to be written in a public format with christians keeping me true to scripture and non-christians reminding me of the secular point of view I'm trying to influence. The whole process is to be transparent, therefore "glass".
