So this is origami bunny that I made.

So this is made from one sheet of paper.

So this 3D form is designed in the computer.

Yeah, so this three-dimensional form is made of small triangles.

So that's how you model 3D models in computer graphics.

And the algorithm is computing some origami folding between these triangles to make it foldable from one sheet of paper to that given shape.

For that, I used some compression geometry techniques to design this.

I designed the software to do so because I thought I cannot make it by myself to arrange all of these triangles.

You have to compute all of the creases all at once.

Yes, that's right.

So the computer tells you the crease pattern where you fold, but you have to fold by your hands.

So this took me 10 hours or so to fold from one piece of paper.

This is it.

So this is the Murari.

That's so cool.

So this is called Murari.

It's a sheet of paper folded along the patterns of parallelograms.

That can fold to a very compact state and then deploy in both directions.

So this has been used for folding the map.

You can just open it very quickly.
