Show HN: WebGPU + TypeScript Slime Mold (github.com/SuboptimalEng)
I made this slime mold simulation to learn more about WebGPU and compute shaders. It's essentially a recreation of Sebastian Lague's coding adventure (albiet with fewer features).

World3, the Public Beta (2012) (bit-player.org)
Forty years ago I had my first close encounter with mathematical models of doomsday. The Limits to Growth, published in the spring of 1972, offered a grim vision of environmental and economic collapse, based on the implacable logic of a computer simulation called World3. For extra nerd-cred authenticity, the results of the simulation were set forth in crude black-and-white graphs reproduced directly from line-printer output.

Show HN: Contagious Beliefs–Simulating Political Alignment (nonzerosum.games)
Humans are social animals, and as such we are influenced by the beliefs of those around us. This simulation explores how beliefs can spread through a population, and how indirect relationships between beliefs can lead to unexpected correlations.
