Raymarching Terrain in Blender

The only geometry in this is a single plane. That's it. Everything is done with nodes in Blender Cycles, and the output is a simple emission shader. Blender breaks when surpassing 36 iterations, so all of these could only be rendered at 36 iterations. Nevertheless, it renders extremely fast and realtime on my new RTX 2080 graphics card! It runs very slowly on the CPU though.
