+### [NeoCogi's Libraries][neocogi-repo]
+
+![Jude3D](jude3d.png)
+
+[Jude3D](https://neocogi.com) is a web based 3D sculpting application.
+It's a WebAssembly application, written in C/C++ and compiled using Emscripten
+but after much thinking the authors decided to move the development to Rust!
+
+Many problems arise when moving existing C/C++/WebAssembly code to Rust.
+The two most important ones:
+
+- The new code should still interop with the already existing code.
+- Payload size matters on the web: your WASM app should be as small as possible.
+
+These led the authors to drop using Rust's std in favor to their own libs (`!#[no_std]`),
+at least until the std library crates are split up accordingly and stabilized,
+for example the `alloc` crate.
+
+The good news is that they are
+[releasing most of the libraries as they make them as open source][neocogi-repo]!
+Also, a [WASM glfw3/GLES2 example][neocogi-example-src] that showcases the libs
+is included ([live demo][neocogi-example-demo]).
