A developer built a browser game called 'Smile Like Zuck' where players match their facial expressions to photos of Mark Zuckerberg. The game uses Google's MediaPipe library for real-time face tracking in the browser. A key technical detail shared is a trick for stabilizing the face bounding box by always cropping to a 3/4 aspect ratio, which prevents the frame from pulsing due to MediaPipe's unstable bounding box output. The project was built at the Recurse Center.
