Ok I just spent 20 mins with an LLM and it got me setup with three Js and adding landmarks to a flat earth projection.

I’ve not the time nor inclination to take it further but happy to share a link to the code if someone else wants to expand on it.

I am a software developer but my curiosity was piqued and the LLM cured that, but happy to zip up the project.

Leaves a lot to be desired as it’s not what you would actually see and more a play on this meme where you can use the camera to set vantage point and see how things would align. We used cubes to represent landmarks so no crazy graphics.
