Distributing particles in circle

Hello there, I've decided to try myself to the sharing of experiences within Softimage Ice :) 
It's not that I intend to learn anything to anyone, but sometimes sharing thoughts  is good, and writing them is even better !

Recently Andy Moorer published a great article http://andy.moonbase.net/archives/859 about putting strands in circles.
This exercise has a different approach with different results. It's just about distributing particles around other particles. ...well the only common point is it deals with circles ^^

First, lets create a simple Pointcloud, call it "Emitter" :
100 Particles aligned on surface.

In another Pointcloud, create an unsimulated IceTree, that will create 10 copies on top of each other of the previous Emitter Pointcloud. We're storing Self.NumberOfclone for later use.

Now, let's see what we have here. (Temporary randomizing the Particle Position for a clearer look).
Notice how the particle ID are organized per particle, we have a clump of 1, 11, 21, 31, etc and further in the picture you see another clump 5, 15, 25, 35...

We want these clumps to be reorganized in 0, 1, 2, 3, 4, 5, 6, etc. per particle clump

Now, let's remove that temporary random. We're going to use Chris Marshall's "Rotate Local" and "Translate Local". (Sorry it's named "OJ" in my compound, but that's just the forename I give to all my added compounds (Hoppe Chris won't mind))

Let's clone, and repeat the Translate local. (Store the 2 PointPositions Values, before and after cloning)

Now you can create an Array of points between those 2 (Check "Delete Source" in ClonePoint)

And with some Turbulences and higher values
