I think there is a lot to improve on when it comes to the visualization of this idea and I'll probably ask ArtAdvice to help or just figure this out on my own, but I gotta ask you'all, do you know of any movies (or shows/manga) that use an environment where gravity is centralized and everything (debris, roads, trees, etc.) just floats in a void of sorts, as their setting? I'm looking for some inspiration for my verse
Context: The Void is three apocalyptic, colliding dimensions made up entirely of debris and surrealistic biomes. Everything within it is floaty, with gravity being centralized to surfaces, making "downward completely arbitrary." There wouldn't be any point of reference for the passage of time either. The world and characters rot, shatter, and corrupt, and the story would be focused on how every character copes with that; With living at the end of times, forever.
Honestly the only thing i can think of was the pysconauts games. There is a level in the 1st similar to your picture
