Trying to make a pleated surface in Grasshopper for Rhino 4.0 (First time)

Hey guys. I'm sorry if I'm doing this wrong but I need help. I am trying to make this shape in Grasshopper. It looks similar to TweenCurves from Rhino 5.0 but I only have 4.0. I want the surface to be able to move depending on attractor points as well. I am just unsure of where to start.
