Voronoi Cell Growth Screensaver
The Voronoi Cell Growth screensaver computes a real live Voronoi tessellation, where seed points grow into cells that expand to tile the entire plane. It is free, runs in your browser, and ESC exits.
How the Voronoi Cell Growth screensaver works
The saver scatters seed points and computes the real Voronoi diagram — every pixel is assigned to its nearest seed.
Cells are drawn expanding outward from each seed until every boundary meets its neighbors.
Once the plane is fully tiled, new seed points are scattered and the growth restarts.
This is the same real mathematical structure used to model cell packing and crystal growth.
A worked example
Two neighboring seed points grow toward each other until their expanding cells meet along a shared straight boundary, exactly as Voronoi math predicts.
Settings & tips
- Accent recolours the cell boundaries.
- Based on the real Voronoi tessellation used across cell biology and geography.
- Each cycle scatters fresh random seed points.
Frequently asked questions
- Is this based on real math?
- Yes — the real Voronoi tessellation, widely used in biology, geography and computer graphics.
- Is a key needed?
- No — it is a pure local simulation.
- Is it free?
- Yes — free, no download, in your browser.
- Does the pattern repeat?
- No — new random seed points are scattered each cycle.
