  I will never understand why people don't lead with the link to the live demo: https://suboptimaleng.github.io/slime-sim-webgpu/

  It's very cool!

  Very cool! I did a similar project last year. Really like how your result looks with the lighting setting on.

  The most interesting results I got were from having multiple "variants" and giving each variant parameters for their attraction to agents of their own/other type. Implementation-wise it was a variant tag for each agent and a matrix of attraction coefficients as a uniform. Playing with the params resulted in interesting behaviors, like one variant chasing another around while they both try to avoid a third.

  If you're looking for an addition to this project, I'd recommend giving it a try!

  Super cool! I was experimenting with WebGPU and various simulations a couple months ago [1] and would love to learn more about your process! Do you have a blog or something similar?

  Amazed that Safari does not support WebGPU even with the latest release. Opened Chrome and it works. Very cool demo!

  I had to read that title several times to make sure that it wasn't the alcohol causing it to register as "Slime Mold."

  Why someone would want to simulate a slime mold is something I don't understand, but more power to ya. =)
