geosign experimental

Plant a signboard in the real world. Others see a coloured dot from afar, and the sign reveals itself when they stand where you stood.

Hold your phone upright and face a direction.
Pick how far ahead and how big the sign is. It stands on the ground, facing you.
Write your message and drop it. Anyone within 500 m sees your dot; within 5 m they can read it.

Needs your location, motion sensors and camera. Only the sign's position and text are saved. Works best outdoors, away from metal.

This version uses the camera to track the phone's motion so signs hold still (8th Wall XR Engine, ~6.5 MB). Falls back to compass mode if it cannot start. Tap the GPS badge in the AR view for diagnostics.
