Antarctica Joy Spiral

This is built from a 0.5° × 0.5° grid of sample points, with the latitude of the points offset by a combination of 1/720th of a degree (to create a spiral), and the elevation at that location (somewhat exaggerated).

There’s a bit of artistic noise thrown in too.

There’s heaps of ‘joy plot’ maps out there, not all of which map elevation. But there’s very few that aren’t horizontal.

Circular/spiral seemed like the only choice for this.
