Snowfall is a macOS menubar app that displays interactive, GPU-rendered snow across connected displays. The main workflow creates a transparent overlay per screen, uses a Metal view controller to manage rendering and lifecycle, and has a renderer update particles before submitting frames to Metal. Users adjust presets and effects in the menubar settings, which persist locally. The README documents window collisions, mouse and wind effects, multi-monitor support, and adaptive rendering; profiling support is also represented. Some subsystem links rely on README statements or the source index because not all implementation files were sampled.
