Hey all! It's been awhile.   I have a couple of paths in an SVG I need to animate using a sinusoidal-like path with a fixed starting point and a variable end point. Imagine a tail flapping about in a strong wind.   If you can point me in the right direction, I am struggling to figure this out. Thanks!   See the Pen oPwyyq by macarius (@macarius) on CodePen.
