UHF X11: X11 Built for VisionOS and Apple Vision Pro

UHF X11 is a new application that transforms Apple Vision Pro into a full X11 display server, allowing users to run classic X11 applications and legacy Unix machines in native spatial windows within visionOS. The software supports external X11 client connections, pixel-perfect rendering with retro CRT effects, OpenGL 3D rendering, and custom font packs, enabling users to interact with vintage computing environments in Apple's spatial computing platform.
