One depiction of cyberspace that's stuck with me is that of the datumplane in Dan Simmons' Hyperion (Chapter 5). It's only a few pages' worth of content, but it's by far the closest description conceptually to Gibson's cyberspace. Notably, the datumplane is envisioned as a highly organic realm at all scales, not restricted to cyberspace's cubes and hard edges. Both contain structures corresponding to the large-scale organization of their societies' data and programs.
