About 1 year ago there was a discussion on this list about Akiko Yamanashi's Pop Twist Box. I got interested in such model and reverse engineered it from a video that was linked in the mentioned thread. I extended, compressed and rotated it many times as in the video.
I kept the folded model in a box I take to conventions to keep my models in and last weekend during one session of the Colombian convention while I was showing it to someone, I accidentally twisted the model and a box was formed. I continued twisting and another box was formed and then another box. You can see what I mean at: http://youtu.be/Zby8JKznd3c I checked other videos of this model and all they show is the model being extended, collapsed and rotated but not the boxes. So did I accidentally discovered this feature? I encourage people to fold this model, because it is a lot of fun. -- Jorge Jaramillo
