Most digital workspaces hide their scale inside nested folders, windows, and activity logs. Universe Screen begins from the opposite premise: if a workspace behaves like a living system, perhaps it should be possible to see and move through it as one.
Universe Screen — Sol Edition is a native macOS and Metal application that turns a selected workspace into an explorable solar system. Folders become worlds, file activity changes the scene, and privacy-filtered Codex activity appears as a fleet moving between projects.
The aim. Make the scale and activity of a working digital environment visible at a glance.
01The problem behind the project
It began with a fascination with making the desktop feel as manipulable as a website. The current version tests a more specific idea: whether spatial metaphors can make many parallel projects and agents easier to understand.
The solar-system metaphor is not only decorative. It provides a stable geography for work that is otherwise abstract: projects can occupy recognizable places, activity can become motion, and parallel agents can be represented without reducing them to another list of status messages.
The current primary user is Josiah. People coordinating many projects or parallel coding agents may also benefit, but that broader use remains a hypothesis rather than demonstrated impact.
02How it took shape
Native Swift, SwiftUI, Metal, FSEvents, a selectable source folder, a Mission Control dashboard, privacy filtering, activity-driven spacecraft motion, and automated tests.
The Sol Edition narrowed an expansive desktop-as-universe idea into a testable native application. A selected folder supplies the world model, filesystem events animate it, and privacy filters determine what agent activity is safe to visualize. The result is deliberately grounded in real workspace state rather than a manually maintained demo.
Josiah originated the desktop-as-universe direction, tactile filesystem metaphor, portfolio decision, and acceptance criteria. GPT-5.6 Sol Ultra through Codex materially generated and iterated the native implementation, tests, documentation, and audit under Josiah’s review.
A working Sol Edition, automated tests, a curated public-safe demo workspace, screenshots, and motion capture exist. The adaptive 30-fps policy measured approximately 29–30 fps on Josiah’s Mac.
03What the project means now
The project is most interesting where the spectacle becomes an interface question. A beautiful spatial metaphor succeeds only if it remains legible, respects private work, and helps its user notice something that a conventional file browser would have concealed.
The project has not yet demonstrated repeated usefulness for people beyond its creator. Public source release still needs licensing, signing, permissions, and release review.
A compelling metaphor is not enough by itself; the scene has to preserve privacy, remain legible under real workload, and prove useful after the novelty wears off.
Integrate the final public-safe case-study media and test the spatial model with people managing multiple active projects.
