oddmon is a lightweight Windows tray utility that brings back the auditory and visual cues of older computers, tied to what your machine is actually doing: a tray HDD-activity LED (green/red/amber on real disk I/O), a power-aware Turbo LED, looped CC0 hard-drive seek sounds, and an optional always-on-top desktop LED panel. Sounds auto-mute while you're in a call (mic in use) and during a configurable quiet-hours window. No telemetry.
