Babeltro

About

Babeltro renders nine classic demoscene effects (starfield, tunnel, plasma, fire, Mandelbrot and others) in thirteen languages, including C, Rust, Perl, SQL and x86 assembly, all running in the browser. Each port is checked against the C reference so the pixels match exactly, which exposes what each language needs to reproduce the same image, such as emulating float32 in SQL or building a sine table in raw WebAssembly.
