Demoscene portfolio
I am active in the demoscene. In 2009, co-founded the Ctrl-Alt-Test demogroup, and since then we've been making demos with extreme size limits (64kB or less).
I am responsible for a large part of the code (around half overall), with a focus on tooling, procedural generation, and animation.
What is a 64k intro?
A 64k intro is a program that generates a realtime animation with synchronized music, and fits into 64,536 bytes. To pack a complete audiovisual experience into that space, we generate everything procedurally: 3D models, textures, music, animations, camera paths... Nothing is pre-rendered; algorithms produce all content on the fly.
This constraint pushes us to use creative solutions: procedural generation, heavy compression, and size-coding tricks. Our engines are written in C++ and OpenGL.
This page includes a selection of the demos I made. Each demo links to more information on the Ctrl-Alt-Test website, including download links and sometimes making-of articles. We often open-source the code. For convenience, I've included video captures, but you can also download the Windows executables run them on your computer.
2025. The Sheep and the Biker
This 8kB intro is the sequel of "The Sheep and the Flower". It also ranked 2nd at the Revision demoparty.
2023. The Sheep and the Flower
The Sheep and the Flower was my first attempt at making a 8kB intro. You might be interested in the article, How we made an animated movie in 8kB.
It was nominated for Best Intro of the year at the 2024 Meteoriks awards, and ranked 2nd at the Revision 2023 demoparty.
2017. Immersion
Immersion is a 64kB intro that was presented at Revision demoparty and at SIGGRAPH Asia 2018. As we were accused of witchcraft, we wrote about the making of Immersion (multi-part articles).
2012. Felix's Workshop
Another 64kB intro, ranked 2nd at Revision demoparty. It was mentioned on Slashdot and presented at SIGGRAPH 2013.
2009. Incubation
Our first demo was a 64kB intro.
With Incubation, we got both the best 64k intro and newcomer prices at Evoke demoparty. German website 4players.de awarded this intro as the third best 64k intro and the best newcomer demo of year 2009.
