Petri: An Artificial-Life Lab You Can Fork
An interactive Lenia laboratory where visitors grow, shape, save, and branch artificial-life colonies in the browser.
- For
- People exploring artificial life and generative systems
- Worth noticing
- Each tick combines 15 kernels across three channels, with a radius-12 neighbourhood and adjustable growth conditions.
Field notes
The lab exposes the simulation’s controls rather than presenting artificial life as a sealed animation: visitors can alter feeding, erasure, creature placement, temperature, nutrients, and radiation, then step through individual ticks. Its method page describes three cell channels, a radius-12 ring neighbourhood, and fifteen growth kernels. The site states that saved moments are written to Arweave and minted on Solana, with later visitors able to load specimens and continue their lineage.
