That's more like it!

Yes, more of the same. But I am getting close to what I want. I switched to nParticles for the curve creation and luckily my scripts worked with just a little tweaking. They started failing when I limited the lifespan of the nParticles, but fortunately Python let's you "try:" stuff.

And tonight after another hour of intense screen staring I have my desktop render an animation of this shape, simply by animating the size of the particles (the radiusPP to be precise, with an expression using the particleID as variable)

So, YEAH! The real work can start: creating an interesting piece of animation using this technique.
