S'poze you have a shape like this,

and you want to draw a line from every point to every other point. OK, no problem.

Just turn on "snap to points" drop a few lines, and you're done in 10 seconds. But what if you want to do something a little more complex,

or something a little MORE complex?

Well if you do, you're going to love my new little script
allPoints.
This script draws all connecting lines groups them together. The original object is kept but is not included in the group. It works on any single selected path item, and it's really, really fast . . . even works on stars and objects drawn freehand.
So, enough babble. Get to it kiddies - make me proud.
