CSC Squared - Whittaker Courtney
Works as if you took a cylinder of the pattern, cut it in half, then stretched it open to the left and right.
Creates a parallel pattern on either side, so it can be thought of as an adjustable 2 sided splits with a curvature stretching outward.
You can copy the code below into a custom_wf or custom_wf_full variation, or add it into the Custom Variation Loader
