The rose mirrors your hand.

Your webcam drives the paper rose: it plays forward or scrubs backward to follow your gesture, no clicks needed — everything runs in your browser, and no video ever leaves it.

✦How to control the flower

Allow the camera when your browser asks — it only watches for your hand; no video is recorded or leaves the page.
Show your hand to the small Gesture Deck window until gold lines trace your fingers.
Open your palm — the rose blooms. Close a fist — it folds away.
