Crater Saturation: Interactive Demo

A playable version of my crater saturation simulation. It uses the same rules and numbers as my v2 notebook: a 500 km × 500 km surface, one 10–20 km impactor plus 100 power-law impactors (0.1–9.99 km, alpha = 2.5) every 1000 years, and a crater counts as visible while less than half of it is covered.

Try it: click the surface to drop a big impact, add random impacts, or run time forward. Turn on erosion or an atmosphere and watch coverage level off lower.
