The spark
A city is alive. We wanted to give that aliveness a body — a form that inhales and exhales with the world outside.

The City
Breathes
A living 3D sculpture that breathes, sings, and transforms in real time with traffic, air, weather, and the collective hum of a city.
Why?
Why does a city need to breathe?
We built The City Breathes because cities are almost always shown as numbers — a dashboard of metrics, a forecast, a chart. But a city is not a spreadsheet; it is a living system with a pulse. The spark was a simple question: what if you could feel a place instead of reading it? What if its air, traffic, weather, and collective hum became something you could watch breathe and hear sing?
The inspiration came from the quiet truth that we rarely notice how the environment actually feels until it is extreme. A clear morning and a smog-heavy evening are worlds apart, yet both collapse into a single index. By turning conditions into color, motion, and sound, the sculpture makes those differences viscerally obvious — you don’t read that the air is stressed, you watch the form redden, distort, and darken.
Awareness
Raising awareness for how the environment feels: air quality and weather become something you sense, not just a percentage you scroll past.
A new medium
Art that only exists when connected to real systems — interactive, networked, and impossible without technology.
Connection
Seeing a distant city breathe builds quiet empathy — a reminder we share one atmosphere, one rhythm.
Concept
A city, felt — not measured.
Cities are usually shown as maps and dashboards. The City Breathes turns the invisible systems of urban life into a living organism: traffic sets its rhythm, air quality colors its skin, weather moves its surface, and social activity makes it shimmer and sing. It is a new medium that could not exist without technology — interactive, networked, and evolving every second.
Interactive
Touch or click the sculpture to change how it breathes. The viewer becomes a participant.
Data-driven
Live public signals directly shape geometry, color, light, and sound in real time.
Procedural
The form is generated by rules, not fixed frames — every moment is unique.
Evolving
The sculpture changes across minutes, hours, and days with the world outside.
Features
What you experience
- Real-time city data from public APIs (weather & air quality).
- A breathing 3D sculpture with morphing, data-driven geometry.
- Generative audio via the Web Audio API, mapped to data intensity.
- Click-to-change breathing styles and live city switching.
- Past-day time-lapse mode to see a city's daily rhythm.
- Graceful demo fallback when live APIs are unavailable.
How it works
How the city becomes motion
| Data | Visual effect | Sound |
|---|---|---|
| Traffic | Breathing rate (7–20 bpm), rotation speed | Breath LFO, filter cutoff |
| Air quality | Surface roughness, darkening, red strain, tremor | Detuned dissonance, grit |
| Wind | Flowing, travelling surface waves | Particle sweep |
| Rain | Softer, cooler light; wetter sheen; haze | Soft noise wash |
| Temperature | Warm ↔ cool color and fill light | Drone pitch base |
Experience
Let the city breathe with you.
Adjust the controls on the right, click the sculpture to shift its breath, and enable sound to hear the data sing. It works with or without a live connection.
