I'm working on a 3D infinite canvas of text, focusing on code. Runs on iPhone, iPad, macOS so they can all act as separate viewports into a space. You can point the app at a repository, download a copy locally, instantly render the entire repository into space in less than a second in most cases, and then fly around and search for text. I just got an optimization working for larger files and it's kinda fun how much even an iPhone can do with instanced rendering.
Im developing it with the use in mind of flying through your code to show others relationships, or edit with a visuospatial look at your code instead of basic 2D tabs and a mind map of which one had the thing you're working on. It's kinda fun to work on the project In the project!
It's built on Swift and Metal but can ready any utf8 text file, minus a few subsections of the Unicode spec (for now).
