Anyone know how to use this script?
 

Hi, I was wondering if anyone knew how to use this script, it looks like a very interesting script, only problem is, I can run the script, but I'm not sure as to how it works, I made a few joints, but they do not seem to be dynamic, any help is appreciated.

Thanks
