Someone coded a cool fluid physics simulation for the ESP32-S3, and people already have excellent ideas for it

A Reddit user discovered an open-source fluid physics simulation project for the ESP32-S3 called Esp32FluidSimulation8x8. Built by GitHub user Vateva, it implements a particle-based FLIP fluid dynamics method on an 8×8 LED matrix, running in real time on constrained embedded hardware. The project includes an incompressibility solver, color presets, and performance/memory stats. Community members are already brainstorming creative uses, such as fidget-toy potion bottles for conventions.
