## Description

Tap the screen and watch a hexagonal cellular automaton grow a breathtaking, six-fold symmetric crystal in real time. Weather data is pulled live from snowy cities around the world — and every crystal takes its shape from the snow falling somewhere on Earth right now.

Temperature →Complexity — The colder the place, the more intricate the branching
Humidity → Density — Higher humidity spreads side branches more densely
Wind → Variation — Stronger winds create irregular, one-of-a-kind forms
Pressure → Ripple patterns — Lower pressure introduces ring-like modulations

No two crystals are ever the same. Nature decides the shape. The algorithm draws it.
The city whose weather inspired each crystal is shown on screen — and you can always find it on a map.
