How can I make a radial noise gradient? I'm trying to create a bump map for an anisotropic metal cylinder. An answer on this post shows exactly what I'm trying to accomplish:

However, when I try recreate it, this is my result (I'm using a vector math node--which looks different, but I don't know of any other nodes that have &quot;normalize&quot;):

Can anyone help me figure this out? Cheers!
UPDATE: Thanks for the help! I combined the two answers, added a little flair, and got this:


P.S. For anyone trying to recreate this later: The bump distance is set to 0.0003
If you just need to create this random circular output, you can actually just plug the gradient node's color output into a noise texture.
Note: Geometry -&gt; Position is based on actual position in the scene, so that may not be what you want to use.  I'm using object coordinates here.

You can control where the effect terminates by using a mapping node.  By default gradient texture generates a 1m radius sphere.  The scale relationship is inversely proportional, so to extend it over an entire axis, you can set that axis to 0.

Increase the scale of the noise texture for finer rings.
