Creating rope with particles - attaching particles and initial state

Hi everyone,

I’m wondering how to create a rope made of particles as Pyroevil did in one of his simulations (https://www.youtube.com/watch?v=XSPwM8Yv6YE).
In particular, my questions are :

How to set the initial state of particles along a curve before starting the actual simulation ?
How to attach the end of the rope to the rotating cube or in general how to attach one or several particle instances to other objects ?

Thanx

Nobody on that topic?
