How Do You Make Those Origami 'pinwheels' that move? ?

Question

Hello!

I've seen in school some people make some modular type origami. It looks like a pinwheel, only the paper moves in and out and gets bigger and smaller when it moves. Its not a pinwheel like.. put it on a stick pinwheel- but it looks like one because of the edges.

Website on how to make them?

Thanks!
