Sbixel is a very simple pixel physics simulator I made to learn Rust.
It uses macroquad for drawing — and I was pleasantly surprised by how simple and awesome it is!

Quick demo (click for youtube link):

⚠️ This project is very basilar and doesn't have much ambition to go anywhere — it's mainly a learning sandbox.

The simulation uses a "sector" system to reduce unnecessary processing by only simulating active areas of pixels.
All settings related to simulation and performance can be found in src/def.rs.

That said, here's the current (loose) roadmap. If anyone wants to contribute, I’d be happy to give my support:

• 🧪 Upgrade water simulation
• 🌊 Improve sand/water interaction
• 🖼️ Render pixels only in active sectors instead of rewriting the whole window every frame
• �� Refactor pixel_already_processed logic — it's very trivial and causes potential bugs
• 💨 Add gas simulation
• 🧱 Add static objects

Make sure you have Rust installed. Then, run the project with (for performance go --release):

cargo run

Feel free to explore, break things, and maybe even improve the code 😊
