The BOS 40th anniversary convention was held at the Kaetsu centre in Cambridge this summer. I studied for my medical degree at Cambridge, so it is always nice to return there. The convention was larger than previous ones, with many more guests and a huge display. Three of the guests were the folders who I consider to be the best three on the planet – Robert Lang, Kamiya Satoshi and Eric Joisel.

Robert Lang

Robert Lang is a superb designer and a mathematical genius. He gave a lecture on designing crease patterns, showing how circle packing can be turned into polygon packing. Which is simpler than it sounds. Always approachable, we had a few long chats about model design, and even about medicine. More of his work is available on his website.

Kamiya Satoshi

Kamiya Satoshi is an origami genius. He is also a man of very few words. Although very polite, I am not sure if he understood a word I said to him. Never the less, he brought along an amazing selection of models. I have seen many of these before on his website. However, I did not realise quite how large and impressive they would be in real life.

Eric Joisel

I have said before that Eric Joisel is insane. Meeting him again confirmed that he was even more so. He laughed hysterically when I tried to persuade him that the embryology of the human pinna (external ear) was essentially modular origami. Anyway, he brought along some of his amazing models, all of which are folded from a single piece of paper per figure!

It was a pleasure to meet old friends, and to meet new ones from the Origami forum, including Anna and Gerwin, two of the moderators. Here is a selection of models, including works by Hojyo Takashi, Hideo Komatsu, Kamiya Ryo, Kyohei Katsuta, Makoto Yamaguchi, David King, Giang Dinh, David Brill, Rikki Donachie, Gerwin Sturm, Anna Kastlunger, Martin Wall, Assia Vely, Les Sunderland, Paul Hanson, Paula Versnick, John McKeever and Edwin Corrie. Also shown is a composite ‘Picasso’s Eye’ folded by all the participants, the back of Eric Joisel’s head, and a goldfish folded by monsieur Joisel.
