I started drawing some things for this week's WCCC prompt "Tiny Islands". I am not sure if I will have the time to continue working on it this weekend. All geometry is generated in real-time using marching squares on CPU.
Added grid, clouds and some sort of flight trajectory.

@voorbeeld It’s like map art. The world map in this style would be much nicer to view than all kinds of maps.

The clouds are made with simplex noise and slow changing z?

@w4v3 I haven't really worked with map art before, but I have to say that the little time I have spent on it now is fun. There is a sense of scale that would not be there if the noise was not placed in a cartographic context.

The clouds are made with the same noise function as the rest of the map, which is a simplex noise with fbm stacked on top.

@w4v3 It actually looks better when the clouds travel along with a (global) wind direction but then looping becomes a bit of an issue.

@voorbeeld Can I ask you what’s fbm?

Thank you very much. And maybe many viewers would enjoy the „moving clouds version“.

@w4v3 it is fractal Brownian motion. https://iquilezles.org/articles/fbm/ does a good job explaining it
@voorbeeld Thank you very much. That’s worth to learn.
