So there are, like, video games that play with the fact that you're looking at a screen, or messing with a controller. There are movies or TV that do similar things. Not enough books play with the physical medium they're in (e.g. House of Leaves). It would be cool to have more books not just user paper and ink as an incidental delivery mechanism for ideas, but as a part of the art.
@benhamill there's the Schrödinger's Cat trilogy by Robert Anton Wilson.
@benhamill RAW messing with the E-W-G "many worlds" interpretation of quantum mechanics as a narrative device. at some point characters become aware they are characters in the Schrödinger's Cat trilogy. :)
@evilchili I see. That's neat. Though something that would work equally well on an eReader or whatever.
@evilchili I've read Illuminatus! ... what's up in the cat books?
