You are in a room with a book. All you can do is read the book, and this will present the text of Moby Dick to you, part by part, with no means to go back and forth through the story. I guess that makes this the least convenient way of reading the book that exists.
I was sort of hoping for an eastern egg if I had the patience to "read more" through all of it, but alas, when you reach the end you just get the question whether you want to quit or restart.
Now there could be changes to the text, either deterministically or randomly, which would constitute an original contribution of mr. McGrew to tale of the whale; but the slight possibility of this is not enough for this reader -- or, I venture, any other -- to actually read through this.
