Landing page captured for the 2026-09-16 issue.

Field notes

Ballpit combines a seed-controlled physics engine with a browser recording workflow: users choose a simulation, set a duration between ten seconds and three minutes, and export in vertical, square, or landscape formats. Its catalogue includes systems such as Color Sort, where shutters admit only matching marbles, and Pendulum Wave, where tuned pendulums drift into travelling waves. The page says rendering and encoding happen locally, while the free plan exposes six of the listed generators and Pro costs US$9.99 per month.
