French demogroup known for its 64k intros and for Shader Minifier, a tool half the intro scene relies on.
The group mostly makes size-limited PC intros, where everything — visuals, camera, music — is generated in real time from a few dozen kilobytes. The 2017 64k H – Immersion, a dive into an underwater lab, is its best-known work and showed how far procedural graphics could be pushed while still telling a cinematic story.
Shader Minifier left an equally large mark. Written for in-house use and then released freely, it shrinks GLSL and HLSL source before packing and now turns up in 4k and 64k intros from entirely unrelated groups. Having your biggest contribution be a tool other people win with is its own kind of generosity.
