This particular model is designed by Komatsu Hideo or Hideo Komatsu, since Japanese tend to put their last name first and now I can't tell which one is which.
You can find the diagrams in Tanteidan Convention Book # 19. P.S. The instructions for this model contains 102 steps. Meh, I know you can do it, though it's not very simple.
I've been stuck up with geometric forms and tessellations for so long, so I decided to make more animals besides the butterfly and the red flappy bird-like thingy I featured before. So, I just started randomly looking at my followers' photostream, and then HOLY CRAP IT'S AWESOME.
When I was young I had made 2 types of origami snails; One has a completely flat shell where I had to draw the spiral on, or else it will look like a drunk man bending his legs over. The other one looks like a slug which came from a birthday party...
