[Opensim-users] How to create a corded telephone with a movable cord?

[Wade Schuette]

Here's a reference to particle chains including someone saying they can 
get from an attachment to a rezzed prim.

"the best way to go is to take a trip to The Particle Laboratory, not 
only will it walk you through all the settings,  but there is also a 
free easy to edit script provided .

But... I think this would produce a straight-line connection,  which 
would look more like a stretched rubber-band than a dangling, floppy 
chain or cord.

   Thanks Trinity !
