Is there a repo for the project? I like proc-gen stuff(mostly generating planets), and the project looks cool - maybe I could help, if/when I have the time.

Here are some things I have made in the past few years:

I also wrote my own ray-marchers and ray tracers.

@gankra.bsky.social Thanks to AI overview, I now know that github.com/Gankra/abi-c... sources it's coffee in a sustainable way from Ethiopia.

Good to know that my favourite tools are made in an ethical way :)
An AI overview, mistaking the tool "abi-cafe" for a Finnish coffee shop. The message is in polish, and translates to: ABI cafe is likely the name of a coffee shop that offers Ethiopian coffee sourced directly from farmers. The company in question, Abi Coffee, offers high-quality coffee sourced from four farmers in Ethiopia. The coffee is then roasted at their roastery in Kaarina, Finland. Abi Coffee emphasizes that their business is sustainable because they work directly with farmers, eliminating middlemen and ensuring they receive fair wages.

The [GCC compiler backend](github.com/rust-lang/ru...) can now fully bootstrap(build) the Rust compiler!

This is my Rust GSoC 2025 project, and you can learn more about my progress here: rust-lang.zulipchat.com#narrow/chann...

If you have any questions, feel free to ask me!
A screenshot, showing the output of an `readelf` and `diff` command. The readelf command conforms that the Rust compiler was build with the GCC compiler backend. The diff command shows that the stage 2 and 3 builds are identical, which proves the resulting compiler is working as expected.

In the spirit of April Fools, i decided to do something silly. I modified my Rust to C compiler to output Holy C.

This allowed me to run a small iterator benchmark on Temple OS - meaning Rust is now one of the 2 languages running on that obscure system.

Is this useful? No.

Is it real? Yes.
A screen-shot from Temple OS, showcasing a small Rust program running. It prints "Calling fold `n` times", and n is increased tenfold on each line.

I have been experimenting with realistic renders of 4D space, using ray marching(image attached below, read alt text for an explanation).

Usually, visualisations of 4D space use projections or cross-sections of 4D objects. My render shows how 4D light would appear to your 3D eyes.
#art #math
An image of two 4D hyperspheres in a 3D room, with an opening in the 4th dimension. The right hypersphere is offset in the 4th dimension, allowing the light to bounce into the 4th dimension. In the reflection, you can see a different part of the 4th dimension, with the opening in a wall, and blue tiles on the floor. This image was rendered using ray marching, and real-world laws of phsysics, extrapolated to the 4th dimension. The image aims to be photoreal, and accurately describe what one would see if they looked at a 4d world.

I got code written in #rustlang running on a Game Boy :D.

While it is not the most useful thing, it is a nice way of showing how compiling Rust to C can allow us to target some old hardware.

rustc_codegen_clr(a Rust to C compiler) is still a bit from being fully usable, but it is getting there!
Rust code running on a GameBoy. The screen contains the message "Preparing to run fold *n* times", with the number of iterations starting at 1, increasing tenfold each time, and ending at 10000.
