Could you build this?

Partial While reading hinge angle sensor APIs and rendering basic UI transforms in Jetpack Compose is manageable, creating seamless system-wide overlay rendering with high-performance frosted glass shaders without root is challenging.

What it would actually take: This requires an Android accessibility or system overlay service using Android Jetpack WindowManager's FoldingFeature APIs to read the hinge sensor in real time. The visual effect relies on custom AGSL (Android Graphics Shading Language) or RenderEffect shaders that mimic dynamic blurred refraction across two display regions without causing frame drops or high battery drain. Developers need specialized knowledge of Android sensor latency, overlay window limits, and real-time graphics/shader pipeline optimization.
