An interactive physics simulator with 1000’s of balls, in your terminal
In plain words
An interactive physics simulator that runs in the terminal, capable of displaying and animating thousands of balls simultaneously. It's designed for developers who want to explore physics simulations or visualize particle systems without leaving the command line. The simulator offers interactive controls to manipulate the physics environment in real time, making it useful for experimentation, testing, or educational purposes related to physics and particle behavior.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
