Cool approach Fabien!
And yeah if you project the curve onto the dome first, then when you twist it the twisted result will still hug directly along the surface if the surface is a surface of revolution and it has the same axis of rotation as the twist axis.
Because with an exact surface of revolution if you rotate any point that starts on the surface around the same axis, the ending point will also be on the surface too since it has that radial symmetry...
I'm still getting used to all the possibilities opened up by Twist and Flow myself! :) Definitely helix-ish stuff and Twist are friends.
