Rainbow Height Map Noise (Animated)

Take a 3D plane and subdivide it to small squares. Apply animated noise to it on the Z axis. Take a gradient of maximum chroma and medium lightness colors, similar to a rainbow, and map it to the elevation view of the noisy plane. Then render the animation, and you get something like this. This could be compared to a geographic elevation map, but with color gradients between lines. It could also be compared to a representation of earth layer evolution.
