Jeremy Shafer published a youtube tutorial for this flapping butterfly card. Paper: 35 cm double-sided paper from origami-shop.com (don’t try smaller paper on your first try). And yes, the butterfly does flap its wings when you pull on the sides of the card :)

The skeleton hand is found in this video tutorial. Paper: 15 cm kami. People like this model a lot, it’s especially popular around Halloween :)

Both models are high-intermediary. They’re not in his books, but he has many other amusing models to fold :)
