Linux running inside a PDF (when opened inside a Chromium-based browser).
https://linux.doompdf.dev/
Built on top of Fabrice Bellard's TinyEMU RISC-V emulator, translated from C to javascript by Emscripten.
Because of course, when Adobe turned PostScript into PDF they intentionally removed the programmable flexibility from it, so google put it back, using javascript.
