A partial attempt, incomplete.
The extrusions need to be longer...
Not sure of the best way to pack circles on a hemisphere...

Anyway, it has been good Moi practice.

Notices that when doing right to left selection highlight, the yellow highlight color often failed to remain yellow...

Is there a way to get the flowed circles to rotate "flat" on the hemisphere? If not pre-rotated, they end up radial. Maybe
there is another way?
