Dynamic Pipe shader tutorial!

My friend has posted a tutorial on creating an amazing dynamic pipe shader! He doesn't have any social media and it was a struggle for him to convince his parents to let him post, so if you can get his video very popular, like it at least, then he can continue producing more videos and be happy. https://youtu.be/-LVOiLUCp4Q?si=NiOvaSwn3Am_OntH
