Cubes let the colors out

As always in Kirigami, only one sheet of worked paper makes the 3D object, and it is still intact. The folding of all the forms out and forward from the prime axis leaves a hole where that material was lifted away from the middle of the paper. The piece shown here is attached to an identical sheet behind it. This is done to fill the hole as though the sheet were both cut and uncut, and it enhances the 3D effect as follows.

Turning the piece,  one finds many unique angles at which the eye projects from a color streak on the 3D figure, back to its place of overlap on the two background planes. Follow the colored stripes outward as the colors merge in certain frames.

The cubes are sitting in a sunny space where they may be grazed by color streaks. Or, maybe the colors have just streaked out of them because they were opened?

 

 

Imagine that!

This Kirigami is bit of a mechanical puzzle: how can this airy thing be folded up from one piece of paper?  I had found this interesting model on Pinterest:

As a novice paper folder, I wanted to diagram the underlying architecture of this piece. Once I had grasped its plan, just to make sure that I had really understood it, I added a fourth floater:

Notice the lines behind it? That’s the blueprint for cutting and folding it. It’s  clearly shown here:

The pop-up action mechanism is revealed by comparing this diagram to this partially folded state:

This material is Frosted Gold, Canford Card; I think it would also look cool in sheet brass. The diagram is available from me upon request.

My learning curve has been greatly eased since I’ve started using an extension called Origami in Adobe Illustrator. It simulates folding of the working model (here, the ‘top’ is to the right):

It can zoom, tilt and rotate the working model. Mistaken lines in one’s structural diagram are all specifically located, so it is a  great tool for self-directed study.
