Reading single point of a Sphere with noise

Hello dear Touchdesigner community =D
First post here :slight_smile: im a “advanced” beginner,
and im wondering how to achieve the design
( I did a sketch in photoshop // see the reed line )

I would like to fix a line onto a single point of my sphere with noise and to have one point of the line moving with the sphere and the other line fixed to one point.

im trining to achieve a kinda cybertek style thing… =)

thx in advance for the one helping.
have a happy day
cheers
