I’m still playing in Houdini and failing to get my head round it. I always suspected my mathematics were a little on the weak side of competence but have now proved it.This is what I’m aiming for, it’s from a file I downloaded from GitHub. I am slowly following the excellent tutorials produced by a Japanese chap called Junichoro Horikawa.I suspect he concentrated whilst in school. I suspect his tutorials will see me out. Mind boggling they are but watching someone write Python fast and explain at the same time is education in itself.Yesterday I found a couple of pristine Butterflies. RED
