YouTuber bluworm took on the task of making a great big octopus puppet for stop-motion animation in a film by his friend Daniel Lennéer. Along the way he produced this informative and entertaining video describing the casting, sculpting, and armature-work that went into it, as well as showing off some of the finished animation (starting around 5:00). Besides the cool propcasting info, I gotta give it up to bluworm for his video editing chops. This is definitely one of the most watchable how-to videos I’ve ever seen, and I’ve seen a bunch of them.
