Gyro
Colour by how a phone is held. Defining tilt zones, and what the crowd looks like when they move.
Gyro maps orientation to colour. The wheel in the panel is a full circle divided into two to ten zones, each with its own colour, and the angle a phone is held at picks the zone.
Snap
Each zone is a hard arc, so a screen is one colour or the next with nothing between.
Smooth
Neighbouring colours blend as the angle crosses, so the crowd becomes a gradient that moves.
Video
The Gyro wheel being turned: zones passing under the angle, the phone mock-up rotating with it.
The other choice is where the angle comes from, and it changes the whole effect.
Organizer
Your device drives and the room turns together. This is the one that paints a shape across the crowd.
Participants
Every phone reads its own orientation and resolves locally. Nothing is broadcast, and the room becomes a field of colours people can play with.
Where the sensor is unavailable or not permitted, a slider covering the full rotation takes over, which is also the easiest way to rehearse the zones at a desk.
