Book arts

I need to make a book for LARP purposes, and while scouting around the net for help I came across various bits of info on different sorts of artists' books (books as art rather than text/only text). I got particularly interested in 'tunnel books', as I had some when I was little that I loved (but can't remember what they were now). I will probably try making one using Chinese papercut techniques. Links for my reference below:

The Owl And The Pussycat
Set of children's tunnel books
Miniature tunnel books (and others)
