🌿 Whisper Vine™

A Tangled Line of Secrets, Laughter, and Light Eavesdropping

Whisper Vine™ is a sculptural network of looping, vine-like pipes that carry sound—whispers, giggles, gossip, or poetry—across unexpected distances. Twisting through plazas, walls, and seating zones, it turns cities into quiet conspirators. One person speaks. Another listens. No electronics. Just wonder.

It’s not infrastructure. It’s urban mischief.

The Philosophy

Public space doesn’t have to shout to be engaging. Whisper Vine™ invites people to listen closer. It’s a celebration of:

  • Low-tech interactivity and ambient surprise

  • Sound as sculpture, connection as play

  • Curiosity without instructions

  • Slow engagement in fast places

It rewards the observant, the playful, and the brave enough to whisper into a vine and see who answers.

Modular System Options

Each Whisper Vine™ installation includes 3–20+ sculptural audio tubes that snake through or around a space:

Root Lines: Tubes that run low through seating, benches, and walls
Climbing Vines: Upright tubes that arch over paths or grow up façades
Hanging Tendrils: Overhead drops that encourage leaning in
Knotted Nodes: Multi-branch points for chaotic whisper crossovers

Design options include:

  • Custom vine shapes, wall-mounts, or ground-buried routing

  • Color-matched or patina-finished exterior

  • Secret speaker prompts or story plaques

  • Community-input ends: “Say something someone else needs to hear.”
