I've programmed a "module" to do a nice bouncing movement in Modul8 by controlling layer position with Processing.
I use a rigid body library of Processing that sends OSC messages to Modul8.
You can see here the result:

You can also move multiple layers.

Enjoy it!
If there'is some interest I can do a tutorial.
