Bendy/Woolly line creation for Linear pattern

Hi all

Using the Bundling demo file for kangaroo I have trying to create bendy paths along a pattern I made of lines in a grasshopper.

The effect will probably be like this -  http://studiomode.nu/mode/384

It is a similar problem to the one in this post

I can't get my script to work, and don't understand why its not working?! 

(It seems to not treat the lines created as proper lines)

I've attached the relevant files, just a heads up, I'm a beginner...

Any advice in either altering what I've got, or tackling it in a new way would be much appreciated!!
