flip matrix i think

Worked Perfectly, thank you very much. Can you explain what the flip matrix actually does or what it is?

Look into data trees in the gh manual. Data in GH is handled by data trees, like a list of lists. Consider it like a bunch of columns ordered in rows. Flip matrix flips that and now it is a bunch of rows ordered in columns. look at the data output. You must understand data trees to really use grasshopper.

For instance, even your original image. You should just use one divide curve - this is the proper way to use gh with lists.

Thank for all the information. For the last example, is it still parametric? How would you go about manipulating the curves within grasshopper in this instance?

It is even more parametric. You manipulate them with lists. How would you like to manipulate them? I would say if you do it the way you are it is actually not parametric (it is too manual / unnecessary copy and paste). 

*If you notice even in Chapulin Colorado's example. He is putting all the curves into one divide curve component. (his curves are from move)

Okay. So if want to shift the data so that the points join all at an angle and the reverse it so I create a triangle pattern, how is this parametrically achieved?

I would solve it like this. By shifting lists and paths.

On an additional note, you can always get the curves out again with list item, tree branch, and explode tree. But overall, you should try and streamline as much as possible.
