Does anyone know how the particles in jitter can follow a path? Or/and how they can go around a wall?

you will have to create your own particle engine for something like this. search the forum for customized particle engine examples.

javascript as well. take a look at the javascript/simulation folder in the examples folder.

java might be the way to go.

Not an easy task indeed, if javascript is the way to go. I was postponing learning that one. Oh, well!
