Peacock with NASA wing

Super zoom! What is this?

This is origami peacock's wing.
How beautiful this pattern is.

This pattern is "ミウラ折り(miura ori)". This pattern is very famous.
What are you think about how it store solar panel of satellite in a rocket? It has to fold efficiently, and must unfold it easily.
"Miura ori" is pattern that lay parallelograms on the paper. It can fold easily and it can unfold simply. "Miura ori" is best.
In fact, NASA use "miura ori".
However, the preparing is bother. I had to fold many times.
First, I folded vertical divide by 32. And, I folded lateral divide by 32.
And and, I folded all diagonal line.
I took 1 hour for just preparing.
When I finished fold all, I gave a deep sigh.
