Erik “kusma” Faye-Lund

I’m a graphics programmer, specializing in low-level OpenGL / DirectX, and other GPU-related development.


I currently work at Fusetools, as a Principal Engineer, leading the development of our compiler for the Uno-language (a dialect of C#). I’m also an active contributor to fuselibs, which is the core of our UI engine.

I’ve previously worked at Hue AS, building big-scale data visualization software for the Oil and Gas industry.

Before that, I was one of the first employees at Falanx Microsystems (later aquired by ARM), where I worked on the ARM Mali line of GPUs, with an emphasis on the OpenGL ES drivers.

You can read more about my professional career on my LinkedIn profile.


I’m also actively contributing to Demoscene productions, in particular under the label Excess. The other currently active half of Excess is Bent “gloom” Stamnes, whom I also happen to work with in my day-job.

I’ve made a lot of demos, and some other notable labels I’ve released under are:

The videos on the top of this page showcase some of these demos.

I’ve also been involved in organizational work in the demoscene, for instance:
