Looking for Fibonacci curve

[micheus]

Is there some way to get such effect?

Scale: I would like to scale vertices from the centre to some radial limit with a gradual effect (strong close the centre and soft in the bondaries).

Rotate: I would like to rotate vertices around a vertice (the centre) to its boundaries, also with a gradual effect. Twist or Tork didn't work for that.

I want to apply these "operations" to this object:


[edit]I change the subject in order to express what I'm looking for.
