Hatching penguin

This model is from Origami for Interpreters by Roman Diaz. Folded from 120x120mm red color paper. The model can be collapsed into an egg to hide the penguin inside.

Cow's skull

With much fascination on skeletons and fossils, I decided to fold this model..

Designed by Roman Diaz and the diagrams can be found in his book, Origami for Interpreters.
