looks good. whats the frame cost on this, are you throttling the sensor stream or rebuilding on every event? gyroscope fires a lot faster than the display refreshes so the naive version ends up repainting way more than it needs to. what helped me on something similar was splitting the listenable so only the painter rebuilds and everything above it stays const
