Live Attitude BY MERRA
Sea Trial · the phone's own motion drives the 3D creel boat
This page uses your phone's own motion sensors. Nothing is sent anywhere.
Hold the phone upright in front of you, like a picture. Press Zero once to set level, then tilt it like a steering wheel to roll her, and lean it away from you to pitch her.
Scan with your phone's camera, then tilt the phone and the boat follows.
