Scripted motion - simulating upstream movement

… been a while since I visited Kirupa! Hello all :slight_smile:

How would you go about coding something like the waves in the header on this page?

I’m hoping to write something that will look a bit like eels swimming upstream but wasn’t quite sure where to start … any pointers would be much appreciated. Thanks!
