Iceland is explicitly geological. Earthquakes and volcanoes, mountains, glaciers, geysers, the aurora: our precarious existence on an only moderately stable rocky sphere is everywhere apparent.
I'm exploring the concentric spheres of geological activity: the inner and outer core, the lower and upper mantle, the crust riding on top: and above that the atmosphere and the ionosphere, where the magnetic field generated in the core interacts with the solar wind to produce the aurora.
Main challenge here is rendering time. I'm trying to build this as a live-rendered animation: at 25 frames per second I only have 40 milliseconds to output c. 10,000 elements. Send more computing power!
