I'm experimenting now, actually. I'm trying to mix visual elements ("artified" pictures) into my chapters. The images all have something to do with the scene in which they appear, and sometimes they give the reader a hint of what is to come. This is something new to me, but I'm sure it's small change for some. Yet, I like the combination.
For example, I attached a picture I've run through the program that I use. This picture is nestled in the chapter of my story where it is pertinent, and my few test readers enjoy the combination of words and images.
This is likely not what you're after, and I'm sorry for that. I'm not exactly breaking barriers here. You're seeking to push your craft, and that's admirable. I wish you luck with it.
