Books with abnormal formatting?

I've asked this question on another forum before, and was curious if anyone else here has read books that do this, but have you ever come across the book that doesn't always follow the conventional "left to right, top to bottom" format (or whatever other formats books in your country usually follow e.g. right to left) most books have? Changing fonts, changing directions, odd structuring, anything? I suppose this might be more of a typical phenomenon in things like childrens' books, but I have heard of some that incorporate it (I believe House of Leaves is the title of one such book?). The most obvious examples I can think up are, as you might expect, childrens' books - specifically the Charlie and Lola series:

Uh... yeah, I don't know what else to add- send in books that are wacky and weird with visual presentation pls *does my best attempt at pleading puppy eyes*

i can't remember the name of the book but i once read one where some pages were upside down and when you read them, it gave the perspective of the other main character. you are right about house of leaves though !! 

what a fun question twin!

there's this book by Murakami that idk if really counts, but the pages aren't like a normal book. while still following the common font structure, it's the creativity within the pages organization that shines the most!

i highly recommend you to check out! :]

Probably not the type of thing you’re talking about but Hubert Selby Jr had a very unique writing style! He pretty much wrote everything in one big paragraph, never used quotations for dialogue, would use a slash in place of an apostrophe (so “we’ll” would be we/ll), and would often not use apostrophes in general (“you’re” would be written as youre for example). He’s got a very stream of consciousness style as well. 

I feel like American Elsewhere by Robert Jackson Bennett kinda fits. He uses different fonts and stuff for different sections and stuff. The main character is also able to see two realities at once, so during those moments he used parentheses to denote the realities she's viewing. There are some sections framed as transcripts as well. It's a lengthy one but a good read

I think what you're looking for is perhaps smtg in the realm of ergodic literature? That's what it's officially called, and books that fall into that category will have those changing directions and odd elements.

House of Leaves is ofc the best example of ergodic literature we have rn but there's many hidden gems that hvnt got the same traction and deserve to.

I've attached a link to an Instagram post below that gives some more ergodic literature examples with visual references of the pages, so hopefully that helps you.

Another one I've read that isn't in that post is Multiple Choice by Alejandro Zambra. Doesn't have changing directions but I think it has different fonts and presents the entire book as a multiple choice exam. Worth checking out as well imo.

A couple more not in the post as well are XX and The Black Locomotive, both by Rian Hughes. Hvnt read them but also I think are worth looking at too.

I'm a new fan to ergodic literature and have been on the hunt myself to read more books in that category, so would also love to hear your recommendations if you have any :)

Mark Z Danielewski's work is based on this. House of leaves is his most popular example but only revolutions takes that even further, but I haven't read it beyond a sample online

To be frank, I see what you are asking for and this is something that I think children's book capture most specifically as a medium. It's very much so their entire design, perhaps you've got an inkling of an idea that might make for a good one based on the nature of your post?

Look at what happened to the Brothers Grimm collection over the decades (they were editors and collectors, not authors btw). They're our catalyst, at least in the US, for pop culture and children's stories almost entirely — but each tale tells darker than that: grim allegories that boil down to a preliminary lesson which is impressionable on children, and emotional to an adult, at least in the original printings and their respective antecedent history. Kind of the "magic" of a fairy tale eh?

Anyways. Ever hear of The Screwtape Letters? By C.S. Lewis. It's an epistolary. As in, the entirety of the book is read as a sequence of letters between a high ranking desk-demon in hell, and his nephew Wormwood as he begins his entry level position working for hell on the surface world as a tempter! Strongly recommend this. It's only read in the side of the uncle replying to his nephew, which is the entire engine for the narration and formats decisiveness.

All my homies fuck with Wormwood...!
