@Natasha_Jay @roytoo this one seems to put most mass at points inward of ends, leading to a ctr calculated left, then right, etc. It was off-the-cuff, but funny.

The resultant mass done when drawing a 5-line star also is interesting: a spike well-inside a broad murderous shelf which either is just above or just below waterline. YMMV.

The ‘but this doesn’t reflect 3d’ part is beginning to tickle my brain.
