This was my entry for the 4k Executable graphics competition at the Black Valley 2025 demoparty, where it placed 1st out of 3 entries. The competition requires that the executable is a maximum of 4096 bytes.
Black Valley is the annual Norwegian demoscene event.
The program started out as an experiment with transparency and refraction using OpenGL shaders. The image is rendered using ray marching.
It was originally made for the Revision 2025 demoparty, but it failed to run on the competition machine due to an Nvidia driver bug.
