Roll a 3D die on your table, through your phone's camera. No app needed.
When your browser asks, allow camera access. The picture is processed on your device and is never recorded or sent anywhere.
Point the camera at the Hiro marker below, printed on paper or shown on another screen. Keep the whole marker in view.
When the die appears on the marker, tap anywhere on the camera view to roll it.
This AR experience needs your camera. Please check that:
