A browser experiment: a webcam gesture triggers an Upside Down transformation.
Privacy: on device detection only, no recording, no upload.

Hi HN, I built this as a small browser experiment.
How it works
• Toggle “Eleven Mode”, grant camera permission, then show a palm toward the webcam
• Gesture detection runs entirely on device in the browser using [MediaPipe Hands]
• Once triggered, I apply a lightweight set of DOM and visual effects to create the “Upside Down” transformation
Privacy
• Camera is used for on device gesture detection only
• No recording, no upload
What I’m exploring
• The practical ceiling of on device gesture recognition in real world conditions (lighting, camera quality, background noise), and what it takes to keep latency low enough for a “feels instant” UX
• How far AI assisted coding can take a real time interactive web experience before manual performance work becomes the bottleneck
Feedback I’d love
• OS + browser + device, and whether it triggers reliably for you
• Any performance issues or onboarding confusion
• Did you find any easter eggs, and which one is your favorite
