This rather nice Japanese site may be a little bit tricky to navigate, but hidden away are several good essays on circle packing and crease patterns. There is a large gallery of Shin Taro's work, along with exploded views crease patterns of his designs.
I haven't seen this site linked to much, which is a shame. Takaaki Kakitsuka presents a selection of his work, best of which are the large galleries of complex insects. There are a few diagrams here, too. He also gives instructions for his insect bases, from which most of his creations are folded.
Occasionally, I or my wife will sell stuff on various commercial websites. This page will automatically list any items. Some will be origami related, some will not. Please note that this is a links page, and all financial transactions will be dealt with on the relevant websites, and NOT through Fishgoth.com. Please also note that we are based in the United Kingdom, and unless the listing says so, we cannot and will not post to abroad.
