Here's an example of what the randomisation options can do with a bit of 
fiddling around. Some of the random shapes looked unrealistic, so it was a 
question of repeatedly adjusting the seed until I got reasonable looking 
shapes. This doesn't use any form of collision detection, so eagle-eyed 
observers will notice that some bits of rope pass through other bits of rope 
and even into adjacent objects in places.

The foreground object uses a very high randomisation setting at about 30 
times the default. The other two are copies of the same coil at about 15 
times the default randomisation (the one on the post is rotated and scaled 
down a little).

To really overlay the coils of rope so that you don't get collisions would 
be more complex. I've had a few ideas, but I'm not sure how difficult any of 
them would turn out to be to implement. Most of my ideas to date would risk 
ending up with some very limp-looking rope.
