Frost Patterns on Glass: Fractal Growth (2D)

A 2D diffusion-limited-aggregation crystal-growth model of frost forming on glass from scratch and dust defects — drag to pan, scroll to zoom, and click the pane to add new nucleation sites.

Chemistry & Materials2DEasy60 FPS📱 Mobile-adapted⇄ 3D version

A simplified 2D diffusion-limited-aggregation simulation of frost crystallising on glass from scratch and dust defects, with a live fractal-dimension readout.

⚙ Under the hood

A simplified 2D diffusion-limited-aggregation model of frost growing from glass-surface defects, with sliders for temperature, humidity, defect density, sticking probability and growth speed, plus click-to-scratch new nucleation sites.
