"geo-viewer" is being updated with improvements. It's a webapp and open source. w3reality.github.io/three-ge…
Rust implementation of Langton's Ant
Simulation from blank to emerging "ladder" at step ~ 10,000, which is explained by Numberphile youtube.com/watch?v=NWBToaXK…

Rust-wasm multithreading capability applied to wasm-demo of the 'plotters' crate (github.com/38/plotters) 🦀 📈.
In this demo, we are plotting a computationally heavy Mandelbrot Set while the main thread is busy with 3D cube rendering.

CA Simulator prototype (with core logic in Rust; GUI in JavaScript).
Rule switching demo:
Game of Life (en.wikipedia.org/wiki/Conway…)
-> Ulam–Warburton CA (en.wikipedia.org/wiki/Ulam%E…)
-> Langton's Ant (en.wikipedia.org/wiki/Langto…)
Developing a Rust crate for writing 2D cellular automata (CA). The idea is for devs to just implement `RuleTrait` to create a new CA.
For example, here's ~30 LoC Lanton's Ant (en.wikipedia.org/wiki/Langto…) working.
Prototyping WebM/HTTP streaming of framebuffer. Initially, using the Game of Life as test pattern generator

It seems, we can generalize it to be an education material on 2D cellular automata j-devel.github.io/demo/life/…
So plan to add more features & GUI.
In es-pack-js v0.5, added `--rustwasm` mode.
To transform wasm-pack generated artifacts into standalone umd/esm modules usable in browsers/Node.js:
$ wasm-pack build --target no-modules
$ es-pack build --rustwasm
demo: github.com/w3reality/es-pack…
Similarly, we can generate an 'esm' module with
$ es-pack build --rustwasm -m esm
example: updated our previous 'rust-canvas-hello'
(xitter.cf/w3reality/status/11542… ) to use 'canvas.esm.js'
(github.com/w3reality/threele…).

We've found that, using wasm-bindgen, developing WebVR apps powered by Rust code becomes pretty seamless. We've made a template hello app showing exactly how to do it.

Made @RIOT_OS `BOARD=native` port of the Bosmoment-style #pinetime firmware.
We can selectively build firmware from the same codebase:
$ make native # with MCU "native"
$ make pinetime # with MCU "nrf52"

Build native @RIOT_OS app with #LVGL + SDL
To facilitate dev/debug LVGL apps on RIOT_OS, added native build mode using SDL backend. Tested on Linux/macOS with mouse event integration.

Native @RIOT_OS running with #LVGL + SDL2
RIOT's LVGL sample is based on the `disp_dev_t` abstracted display. So for native development, tried implementing a custom one using the SDL2-based driver github.com/lvgl/lv_drivers/b… It works.
Started writing a firmware targeting #ESP32 IoT chips in Rust. Following an article dev.to/jeikabu/matrix-voice-… we've got a recursive `fib()` function demo working.
Reworked on API in three-geo v1.4.
Now, basically, a single line of async call is suffice to build a satellite-textured DEM ready to be rendered with three.js.
