I'm so curious but the article doesn't mention: how were these splines "defined"? In other words, if you have to reproduce your work for a new draft, how do you make sure you draw the exact same curve? (Without tracing the prior draft.)
Are there "control points" like Bézier curves have? Do those have anything to do with the placement of the whales? Or was this all just done "by eye" so that these splines assisted in drawing a perfectly smooth curve, but the result was just trial-and-error to find a curve that looks good?
