Negative Space--a literary pensee (are there nonliterary Pensees?)

I've been reading a novel lately by Jacques Roubaud called The Great Fire of London, which is essentially a progressively-constructed novel about everything other than the Great Fire of London. It's essentially a novel about writing. Which reminds me, in a sort of way, of a draft I read in memoir class, wherein all but the main issue at hand was addressed in the narrative. It seems a rather tall order, but I think it would be a very interesting writing project to write about everything other than the idea at hand, wherein the work forms a sort of mold, surrounding a void that is the actual point of the work. The idea would be there, perfectly formed, only in what the work is not. It could even be a topical subject, such as a project that could illustrate the current political situation, wherein all is talked about in detail other than the elephant in the room. The musical group Elbow have already done such a thing with the cover art for one of their recent slew of releases...though I can only find the positive space version of their cover art. The negative space is available in tiny form a third of the way down on this page, for the fugitive motel release.
