As one of the most intelligent and advanced invertebrates, or as a delicious appetizer, everyone loves the octopus. This model was spontaneously invented in response to a challenge at a party. With its rotational symmetry this model is a forerunner to the whole origami from space approach.

This fascinating shape can be seen either as a stellated octahedron or two mutually intersecting tetrahedra. This model is a compound, made of four sheets of square paper, each containing one corner of each of two tetrahedrons. Different methods of creating the module render the final shape in similar or contrasting colors. I have been working a version from a single sheet with the color change.
