Howto create Helix sphere

Does any one have any idea how to create helix sphere?

Use Rhumb lines:

They have a travelangle/bearing and the longtitude where it passes the aequator.
Calculate the vertices, offset the longtitude where it passes, calculate vertices again and make a poly-loop out of it.
Duplicate and rotate it multiple times. Done.

Or directly go with a spherical helix:
