If you're inspired by spacy things, why not just use flat ethernet cables ON the wall, which come in all colors? Then combine them with triangular LED-panels (powered and brightness-/color-controlled over those cables) at places where they have to turn sharply, or branch from a little switch (hidden behind such a triangular LED-panel)? If you don't get what I mean, search for pictures of 'Nanoleaf' to get an impression of the many forms you can build. That looks rather OK for my tastes. And is simple to implement, up to 1Gbit/s. Not because of the limitations of the cables, they go up to 40Gbit/s in flat form factor, but for the small switches, or SBCs which could be 'abused' as such. Anyways, Nanoleaf or any others don't come ready for POE, so have to be modded, but not by much. Controlling them over ethernet requires more modding, but not that much either. One could also use the remote, and just give power over POE.
