Could you build this?
Partial Displaying a canvas in HTML is trivial, but compiling legacy C NetHack source code and its isometric Falcon's Eye frontend into WebAssembly with Emscripten requires specialized systems programming skills.
What it would actually take: A developer needs an Emscripten toolchain, legacy C build systems (Makefiles), and NetHack 3.x C source code patched with the Falcon's Eye isometric graphics engine. The difficult part is mapping old X11 or SDL1 graphics and input routines to SDL2/WebGL and browser event loops while handling C memory management and asynchronous I/O in WASM. It requires deep C/C++ compilation, POSIX-to-web emulation, and debugging tools like lldb/dwarf in Chrome DevTools.

Same idea, different domain
Nobody's really built a hardware & robotics tool for Horizontal yet.
