only bad thing is that the "song" become VERY enoying when playing around in the program for any longer periods of time ;)
You can disable the sound (press F1!!) Yah like add some movement to the particles - ie by themselves, interacting with each other, rather than just mouse control. I didn't mean animating the blob field, although that's a possibility.
Ah, I may explore it.. Also, thanks for sharing the source.
