I found this very nice stop-motion animation on YouTube. It is a song called I love buildin'
featuring two cowboys. These are such nice figures I tried to model the head of one of them and provide instructions on how to build here.
The model features an unofficial part, buffer exchange, rotation steps, the LPub Remove Group metacommands, ignoring submodels, treating 2 elements as one part and more. Study the code to learn!
