Pulse of the World
Study
Working question: can global metrics be understood as rhythms rather than only numbers?
The thing is a web app that turns rates into pulses. Births, deaths, and other metrics become time-based signals.
The current page explains the app. The study note still needs the reflection: what pulsing makes easier to feel, what it distorts, and how data changes when it becomes an interface.
Feel the numbers.
We drown in statistics. Billions born, millions dead, trillions of emails, numbers so large they lose all meaning. Pulse of the World is an attempt to make them tangible again.
The Idea
A dark screen. A grid of cells. Each cell represents a global metric: births, deaths, deforestation, coffee consumption, CO₂ emissions. And each cell pulses at the rhythm of that metric’s real-world rate.
A birth every 238 milliseconds. A death every 500 milliseconds. One hundred trees felled every 211 milliseconds. Not as numbers on a page, but as a heartbeat you can feel.
The Counter
Below each pulse, a counter runs from the moment you open the page:
Seit deinem Besuch: 1.247 Menschen geboren
Five minutes on the site. 1.260 births. 600 deaths. 142.500 trees felled. 12 million emails sent. The numbers accumulate in real time, tied to your presence. You did not just read a statistic. You watched it happen.
Scaling
Not every metric can pulse at its raw rate. 4.18 million emails per second would be invisible. So each cell pulses at a meaningful unit: one pulse per million emails, one pulse per ten thousand cups of coffee, one pulse per single human birth. The unit is displayed on the cell. No deception, just sensible grouping.
Categories
The grid organizes into five categories, filterable with a click:
-
Leben & Sterben: Births, deaths, deforestation, child mortality
-
Technologie: Google searches, emails, WhatsApp, smartphones, e-waste
-
Fun: Lightning strikes, Lego bricks, coffee, music streams
-
Wirtschaft: Oil, CO₂, Amazon orders, plastic bottles, food waste
-
Kultur: Books published, Netflix hours, new songs, Wikipedia edits
Design
Black background. Colored dots pulsing in their individual rhythm. No chrome, no navigation, no decoration. The data is the experience.
Hero cells (births, deaths, CO₂) span two columns and two rows. Smaller metrics fill the gaps. The grid breathes.
Every source is linked. Hover over a cell, and you see where the number comes from. Transparency is non-negotiable when you are visualizing the world.
Tech
Vanilla HTML, CSS, and JavaScript. No build step. Metrics defined in a single JSON file. The entire thing runs as a static page, no server required.
