I love the work Memo Akten has done with  MSAFluid, I would like to be able to use Kinect and have the particles emit from a person's hands as he moves them around (in place of using the mouse).  I have purchased "Making Things See" and was able to use one of the tutorials to use the Kinect to attach a dot on a person's hand, as well as draw a line by moving the hand around.  But I do not know how to integrate something like MSAFluid with the drawing sketch to replace the line with a particle emitter.
