I took a workshop this weekend at the Center for Book Arts here for making Hedi Kyle's Secret Belgian Binding structure. The story behind this binding is delightfully nerdy and involves it being discovered and reworked by either Hedi Kyle or Anne Goy, depending on which blog you read. I'm on team Hedi myself - I have a major bookcrush on that lady. She designed the blizzard book, one of the very first structures I tried to muddle through while at my office job using xerox paper and stealing company time.
Here are some great clearly written instructions, if you want to give it a try, and this page has some good tips as well.
