You could achieve something similar by using VR to embed 4D environments in 3D space - I’d be very surprised if something like this hasn’t already been tried tbh

On machines where I have to use windows I run start10 to replace the start menu with something a little more bearable. I imagine there’s a FOSS equivalent but I bought a license years and years ago so I’ve never bothered to search.

What I’d really love is a script/shader/plugin that lets me do this within the engine - separate out the sprite and its texture so I can swap them out on the fly. Shouldn’t be too painful to implement but it’s not something I’ve seen anywhere before
