It's called the Kawasaki Rose. Done with only one piece of paper and the infamous Kawasaki Twist fold, it isn't an easy origami.

I'm particular fond of modular origami - you made little pieces (units/modules) and assemble them together. The first two have 30 pieces, a standar number. The third one was a bit of a pain to assemble when it started to close, I had to use tweezers for help.
This is strip origami (insert joke here). You use strips of paper instead of the usual square/rectangle/triangle.
I thought this vase was going to be difficult but it came out quick and simple. I love how strong it is!
This is a silly one but I thought Miyazaki's fans would like it. :)
