Yes, sorry, it's another update on the force-fields experiment...
This time we're targeting Flash Player 11, using the ND2D engine for the rendering and a bit of post-processing.
The background noise is a post-process effect I based on one of the 2D PixelBender shaders by nicoptere. I plan to cover the process of writing the AGAL code for it in my next post.
There's a little interface where you can tweak a few parameters to control the motion. When it starts, all the parameters are set to animate from their minimum to maximum - disable the 'tween' checkboxes to stop the automation and change parameters manually.
Try it here.

[...] might have seen it already: Mike built some cool force field experiments with ND2D a while ago. Now he opened a github project called Napoleon. Napoleon is a 2D physics [...]
