[Origami] Origami USA and COET?

Several years back I recall Origami USA working with an organization with the acronym of C O E T ; does anybody remember what it stood for? 

[Origami] Looking for info

I'm looking for info on this model to identify the name of the model and possibly the creator. I learned it at Centerfold 3 yrs ago during after hours folding and have lost that information. It's made from 4 fish bases mingled together and the result is the same on both sides. Great for Mandela
