Monocular Light Fairy.

One image, a moving light. This experiment estimates the shape of a scene and lets a glowing fairy fly through it — using a still photograph or the camera on your device.

01 / Start with a photo

Try the sample, or choose a photo from your device. No camera needed.

02 / Try your camera

Choose Live camera, then Start. Allow camera access when your browser asks; switch front or rear where available.

Preparing WebGPU…

Drag or tap the image to pin the fairy; tap it again to resume flight. Scroll or pinch to move the light in depth. Use View to compare the original image with the lighting effect. Photos and camera frames stay in this tab. Stop camera or Change source ends camera capture.
