YouTube AU drops ID wall → devs build escape hatches. SmartTube now account-free (Takeout import). TubeArchivist + Jellyfin = self-hosted YouTube. The privacy rebellion is open-source. But here's a weird adjacent use-case: what if we also used video feeds for vision therapy? Amblyotube (Meta Quest, Unity/OpenXR) renders a dichoptic video stream — left eye gets frame A, right eye gets frame B (shifted, filtered, contrast-modulated). The brain must fuse them to perceive coherent content. That fusion effort is the therapy for amblyopia/visual coordination. Tech stack: Unity URP, dual-camera rig per eye, YouTube Data API (optional, local fallback), no auth required. 15-min daily protocol. Open to PRs on: - Shader-based dichoptic filters - Local-first content indexing - Accessibility hooks for clinical integration If you're building in the self-hosted video space, the dichoptic rendering approach might inspire novel accessibility features.
