Jorge Pardo gave a workshop for his flexiball at the CDO Convention 2009. I actually didn't join it, but it motivated me to fold one. I had this strange idea that I shoulf fold a small version, and started with squares that had a side length of 3.75cm. When Jorge saw this, he told me it was too small, and that you would not be able to flex it without it coming apart. And of course that just motivated me more - plus, I'd already done about quarter of it, so I didn't just want to stop.

Satoshi Kamiya also taught a workshop at the CDO Convention 2009 for his fish. It was somewhat - let's say unconventional: he said he'd teach "John Montroll style": he handed out diagrams and paper, and then was there for questions. He'd scheduled 3 hours, but most of us were done with the model after about 2 hours, and I am surprised by how nice my first fold looks. It's surely connected to the awesome paper Satoshi gave us. He said it was gampi paper. It was quite thin, but strong, and took creases extremely well.
Surely one of the highlights of the CDO Convention 2009 was participating in origami workshops lead by Satoshi Kamiya. He taught this rabbit, and it wasn't quite so easy to get a nice finished model - not due to the complexity of the folds, but rather because there were a lot of judgement folds you had to make. So this is a model you have to fold a couple of times to get a feeling for how to place the creases to get a rabbit-like feel in the finished model.
Alessandro Beber taught this octagonal bowl at the CDO Convention 2009. I especially like that you can play around with the finished model to get different variations: you can change the height of the bowl, and depending on taste have a star shape, or sink the corners of the star. No additional creases are necessary.
I'm actually thinking about making a video on this one, and will have to contact Alessandro on it.
