modular origami: spiral shellfish

I must say I really like Fuse’s diagrams (as if you hadn’t noticed that already…) and this shell is just so easy to fold and results in a very cute “shape”. I mean it’s spiraled, it’s 3D and has that cuteness and beauty of the real shells.

You can find this diagram, once again, in らせんを折ろう/ let’s fold spirals. The white and gold one was the first and was made with 10×10 cm wrapping paper, it results in a 3x3x7 cm shell, approximately. The white was made with a japanese white paper, very thin (I believe it’s between 40 and 60 grams per square meter; so thin that it is slightly transparent) in 16.5 cm squares. This shell is 5.5×5.5×12 cm. Both were made with four units each. Cute is the word of the day! Or perhaps I should say かわいい? :)
Oh the name of this shell is 風化した貝 which I don’t know how to exactly translate so spiral shellfish it is… A note: I think it translates into weathered shellfish but I don’t know if that name is widely known or not so bear with the lame translation.
