Launch modes

Section Rings mode

Section Rings

Each analysed section colours a band of the tunnel wall.

Beat Rungs mode

Beat Rungs

The beat grid as ladder rungs, with heavier downbeats so bars are countable.

Energy Profile mode

Energy Profile

The tunnel radius IS the energy history: a profile you fly through.

Marker Gates mode

Marker Gates

Section boundaries become solid gates the camera passes through.

Look-Ahead Map mode

Look-Ahead Map

A flattened strip chart with a playhead: past behind, unknown ahead.

Structure Ribbon mode

Structure Ribbon

One continuous ribbon whose twist encodes section changes.
