enhanced novels? digital ergodic literature?

That is why I mentioned House of Leaves as an example. Many would not consider its use of graphics as adding nothing.

Yeah I pretty much agree, and this mis/over-use of graphics and sounds is exactly what I’m not so interested in finding. That’s what makes the search a bit difficult. I can’t just look for “enhanced novels,” or “interactive graphic fiction.” That turns up things that are too much like the first example of SHERLOCK I mentioned, and too much like what you are pointing out.

I think Device 6 and Blackbar are more in line with what I’m thinking. Something where the enhancements are essential to the project and not just decoration.
