For an art-project I'm currently working on I want to design a Gun. As I was trying to figure out how to so this, I stumbeled upon this model. A simplye tube with an L shape. I folded it from one A4 sheet. This is my first attempt, so please forgive me the imperfections of this fold. What I like about this model is the fact that it isn't flat and the way I made it hold itself together. Also it should be easy to make S and U shaped tubes with the same aproach.
Here's some neat footage of the Origami Museum in Tokyo. I wish the video quality were a little better, but I still love checking out these origami villages and stuff. :D
Sadako Sasaki was a Girl from Japan who apperently survived the dropping of the A-Bomb over Hiroshima unharmed. But when she turned twelve it became obvious that she had leukemia as an aftermath of the A-bomb. As she was in hospital friends visited her and one of them folded an Origami Crane for her telling her the story of the 1000 cranes that grand you a wish. Hoping for cure she began to fold. At this point stories begin to vary some say she made it and continued as nothing happen after...
