Open Source software developer, photographer, drummer, and electronics tinkerer


Hi, I’m Sybren Stüvel. I work as Blender developer, where I lead the Animation & Rigging module and work on Flamenco, the render farm software. Apart from my work on Blender, I also develop various other Open Source projects, such as Flatterer and Skyfill.

On this website you’ll also find other nerdy things, like my own DIY electronics projects, my photography stuff, and my archive of UnrealTower, my old Unreal Tournament modding site.
