Real mode demo inspired by CMatrix in 187 bytes

Real mode demo inspired by CMatrix in 187 bytes launched on March 16, 2016 with 10 votes, #2,037 of 4,409 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 10 years on.

In plain words

This is a tiny demo program inspired by CMatrix that creates a Matrix-style visual effect in real mode. At just 187 bytes, it's an extremely compact piece of code designed for programmers and demoscene enthusiasts interested in low-level computing and retro programming techniques. The program was launched in 2016 and showcases what's possible within severe size constraints.

    I recreated 90s Mode X demoscene effects in JavaScript and Canvas2025 · jdfio.com · ▲189

    After 25 years of writing software, I was feeling nostalgic for the kinds of things that got me into programming in the first place: the old DOS demoscene. I spent a weekend seeing if I could recapture some of that INT 13H VGA magic using today's web tech, but with the old-school constraints of doing it from scratch. The result is this portfolio of ten classic effects running in a single HTML file. It's all vanilla JavaScript writing to a element, with no external libraries. It was a fun challenge to implement things like: * The color palette cycling and smooth fading in the Plasma demo. *…

    We ported pbrt-v4 to Julia and built it into a Makie backend. Any Makie plot can now be rendered with physically-based path tracing. Julia compiles user-defined physics directly into GPU kernels, so anyone can extend the ray tracer with new materials and media - a black hole with gravitational lensing is ~200 lines of Julia. Runs on AMD, NVIDIA, and CPU via KernelAbstractions.jl, with Metal coming soon. Demo scenes: github.com/SimonDanisch/RayDemo
