Star, Triple Kawasaki Twist.

[Razzmatazz]

Here is something I made in church. It's pretty much a grid folded into a kawasaki twist 3 times, each in a different way. It does kind of look like a swastika but not quite. Now that we've established that; no more comments about it. I dunno if I should make a CP or if it's pretty easy to make itself. It's kind of ugly with the grid creases, but hey, it makes it easier to fold.

Congratulations on your independent discovery. That principle was used by Helena Verrill to create her Ziggurat:
Here collapsed:

And here erected:

LOL, must have been a boring service then.

Nah it wasn't a boring service. I just always need something to do with my hands so I make origami out of the bulletin.

And that's a cool pyramid thing.

It's just called a "twist fold" or "square twist"... Kawasaki didn't invent it! In fact twist folds show up in a couple traditional models.
