There are lots of 'Brian Chan's out their. If you google 'Brian Chan', the first link you get is to his origami website - that is how good he is. This website has a stunning array of complex origami.There are also large numbers of crease patterns, too.
Jason Ku presents a gallery of some of his superb work here. Some have crease patterns, which are phenomenally complex. There are some familiar models, which have been diagrammed in OUSA and Origami Tantidan convention books, too.
This is a website linking to Hitatori Koshiro's Origami and translation work. Although the site is a little difficult to nagivate (for someone who doesn't speak Japanese), if you look hard enough, you'll find some interesting designs.
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.
As well as folding paper and working as a doctor, I enjoy taking photographs. A lot of my photograph is of local wildlife in West London, or of animals at various parks and sanctuaries. As you can imagine, a lot of my origami work is influence by these photos.
