I just picked up the book yesterday, and I am very excited about it. However, I do have a question about the blip page. Is the method to seeing it similar to that of the old "Magic eye" pictures, where you have to cross your eyes somewhat? Or is this way off the mark? The reason I ask this is because I can definitely get a blip page when I pretend I am looking at one of those pictures. Also, is it ok if there is text in the blip page? or should it be blank (a thin blip page of only the margins)?
