Peep
Hole
... and the movie ends.
The reader is left turning the page to 321 and looking at a dot. A period maybe? A quarter in the floor (pg 305)? The last fading images of the movie that had just ended (pg 307-3111) and we are left withnothing more than a black dot.
... highlighted by light.
Through the use of the negative space a voide is left, a vortex of sorts. There are no other options than to look inside. The negative space of the page highlights it and draws the reader in, tempting the reader to put their eye to the page physically and see if there's anything behind the hole.
... and then the page closes.
While we believe that we still have control of the story, the pages that we physically turn, are we not stuck inthe story. How many times did you catch yourself thinking about where Karen was? How Navidson was doing now that he was burning up the book that you had just had in your hands. Through the haunting of House of Leaves, the characters stay rent free in our minds even after we put down the book.
... it's a peephole.
One page before the introduction of the minotaur we are left with an invitation. Us the readers as well as the minotaur are left to look through the peephole and see what's left of the character's trying to find each other. To see what is left of the men who are so determined to get out of this house that will destroy them.
... we insert ourselves into the pages.
This black dot is a peephole that allows us to look through a different angle of the house into the characters self created mayhem. We become a character under control of Mark. We insert ourselves into the pages and become bound to the story like all the other characters we thought we had physical control of as the reader.
