I've been recently curious about FUI's seen in sci-fi games or movies, it seems the conclusion on these UI's is that they are flashy and very unpractical. But one concept that I seen have seen used throughout most of these UIs was laying out UI components on top of a dot grid or just bordered grid, and this didn't seem outlandish to me. The concept of laying out UI elements such that they "hang" on to this strict grid system seems like a good way to stay consistent and indicate structure. But I suppose seeing a dot grid backgrounding the UI might prove too distracting? This concept seems reminiscent of the recent Card UI trend, maybe that's the practical application of this concept?
My question is: Why is the concept of using a strict grid systems (found in futuristic UIs) which involves laying out UI components on top of a visible dot grid good or bad in contemporary UIs?
I would also love any links to analysis regarding to pros and cons of FUIs as I haven't really found any.
For reference here are examples of FUIs that (losely) use this concept:
