Ryan, the control points are what you use to "bend" or "stretch" the hose.
Moving the control points draws the hose along with it.
The original bezier curve generator used two control points, as well as two
endpoints (the ends for the hose). I made step by step instructions for how to
use that program, and I suspect that the principles are probably similar in
Johns spreadsheet.
It _might_ help you if you try to use that original system. That will at least
give you an understanding of the principles involved, and some sense of what to
expect with the spreadsheet. Once you have a grasp of it, you could then apply
that knowledge to the spreadsheet to make a great hose.
