Hey guys!

First of all, this is my first post! So hello to everyone
My name is Raynor de Groot, I'm a dutch graphic designer and filmmaker. I'm working on a motion graphic at the moment and I'm kinda stuck.

Here's the problem:
I could use some advice for a difficult mograph project using Trapcode Particular

The problem is illustrated with some images that state the problem more clear than I could do in words.

In short:
I want to build up different images (using the same animation) from particles which are emitted from the center and are perfectly aligning. Particles need to be the same size.

I hope you guys can help me out!
