Title: Canyon Echoes — Shout Into Deep Time
Creative prompt: A red-rock gorge 300 metres wide where shouts return two seconds late, once per wall, across six painted strata from Kaibab limestone to Vishnu granite. Voice power sets ring speed and shakes pebbles loose while dusk reddens the sky. The cursor aims each call like a conductor.
Design description: Field-journal split with sand control column and dark gorge canvas; call-type tabs, shout trigger, power/wind/dusk sliders, and echo ledger beside a five-band strata explainer strip.
Visual techniques:
- Canvas twin-wall gorge with six strata bands and river gorge
- Expanding double echo rings with delay staging and song sustain
- Soaring swifts, drifting dust, dusk-remapped sky, and aim dashed line
- Power-driven ring velocity and rockfall dust bursts
- River glint and live ring-count river gauge
Interaction model: Call tabs change echo count and speed, sliders drive power/wind/dusk, canvas clicks and shout button cast echoes from any point, and cursor aims while dust and ledger track consequences.
