It mentions that the visualization can be seen at the bottom of the post, but I only see the video and image gallery. I have WebGPU enabled in Chromium.

Steps to run (in Chrome):

  git clone https://github.com/craftlinks/Notebook

  cd Notebook/particle-lenia

  node --version
  # v24.3.0

  npm i

  npm run dev
