Hi During OUSA 2018 Sy Chen was in the same suite I was and he was the roomate of a friend. Sy gave my friend a present that was a bicolor masu box, my friend and I unfolded it carefully and I learnt how to do it. I just folded one that can be seen at http://www.flickr.com/photos/georigami/30919508778/
I think it is a clever model and I don't recall having seen it before. So do any of you know if another model with these characteristics? Also, does anyone have Sy Chen's email address? I checked his webpage but could not find any contact information.
