WG-Origami

The theme for Origami Dan's May design contest was prehistoric human; or anything related to it. I was tired to design complex model, and aimed to make simple model. So I thought of making this roasted meat. Jang Yong Ik's asian black bear and Syn's Adult Syn having a good time.

Crease Pattern Design I made this for April 2021 design contest in Origami-Dan. The theme was "same subject", which later was decided as "parasitoid fungi species affecting invertebrates".

I had the opportunity to join FoldFest Spring 2021, which was hosted by Origami USA in online. We had to pay $40, but looking at the content and opportunity to meet people, I think it was worth it. Through this post I will share my experience on attending it. Prior to this, I had only one origami conference experience which was on Indonesia back in 2014. I felt so good when I met people with same hobby and we can discuss and share knowledge. In FoldFest, I had the same feeling. Even though we can't walk around and meet people in person, the committee of FoldFest used a platform called gather.town, which allowed us to create our avatar and explore the premade map. When we walked across someone, within certain proximity, a video call screen will pop up and we can see/talk to each other. To some extent that substitutes the feeling of meeting in person during conference.

Here we go with the prompt #21 until #27. #21 Ornament: Fleur de Lis The requirement of 3 large flaps and 3 smaller flaps is ideal for bird base with one corner split. The challenge here is to make the curved structure on the sides. I have no other idea apart from doing the loose reverse fold.  #22 Teeth: Helicoprion Helicoprion is a prehistoric shark with teeth on lower jaw that looks like circular saw. I don't have experience on folding teeth apart from Takagi's mosasaurus which used a long flap that gets pleated. To follow that idea, I reserved the entire 1/4 corner for lower jaw. Naturally the upper jaw can be put in the middle to make a bird-base like structure: The remaining corners somehow should form body, tail, and other fins. It doesn't matter which corner should be used for the tail, the body length will the same since any remaining corners will yield the largest possible circle. I picked the lower left and now it became like a full blown bird base. I made a bird...

Here we go with the prompt #14 until #20.

Coconut crab is a species of hermit crab that has abandoned the lifestyle of carrying gastropod's shell. Instead, it grows hard exoskeleton and curl its abdomen underneath. This allows their growth to be unconstrained by gastropod's shell availability. As such they can get really big. Unfortunately their existence is on vulnerable state due to habitat loss and over hunting. The Origami-Dan's design contest theme for January was "improvement". We can submit improved version of our previous design. I guess it's good thing to do to start the year, to look back and see how much we have improved.

Here we go with the prompt #7 until #13. I didn't have submission for #8 and #9 because I was working on the Discord bot, later named as "Robori" after "Robot" and "Origami". This bot is used for automatically pick the challenge prompt and do book-keeping of submissions per users. The daily challenge now fully runs automatically, like a clockwork ninja.

I joined another origami Discord server beside Origami-Dan, and it is called Origami Design School. I will just call it DS for short. It focuses on design aspect and less about fold, material, and other stuff. One of the main activity in DS will be daily design challenge. Each day there will be a prompt, typically a word, and we have to design something that has something to do with it. For example, if the prompt is "fish" then we need to design & fold any kind of fish. It has to be new design, and delivered within the day.

You might have seen a pleated structure incorporated to a model. It is commonly used in insect for the abdomen, animal's ribs, or array of "spikes" on top of animal like crocodile. I know how to construct it on boxpleated, but I wonder if the solution on non-boxpleating is generalizable. I remember that I've folded Kamiya's dragonfly and inoshishigami which uses that structure. On inoshishigami, the rib pleat starts from single flap. This flap is squashed, then slid to top; as if now there's a river separating the flap. That step is repeated until that flap is split into 4 smaller unit flap, separated by rivers. However, in the last pleat Kamiya prepared squash on each edge so the final flap sliding can be performed. On dragonfly, the process is similar but the flap sliding is more prominent. Based on those models, along with warm shower, I started understand how it works. Basically, we can split a 1-unit flap into N smaller flaps with length of 1/N unit, eac...

As mentioned on previous post , bird of paradise is actually a group of bird species. Each species has their own exaggerated plume, feathers, call, or dance to please the females. Another one that attracted me is King of Saxony Bird of Paradise. This bird only exist in eastern part of Indonesia, and I didn't even know it exists. I guess it is not popular worldwide either. Photo from  Berita dan Ilmu Pengetahuan I want to design this bird because of the display feathers, which provides interesting challenge. Those feathers are absurdly long, reaching twice of the body length.
