I know the model that Michael was demonstrating. I first learned it at the BOS 30th anniversary convention. The model is Sanny's Zoomerang by Sanny Ang. Claire Chamberlin is tentatively scheduled to teach it on Saturday afternoon at this years BOS 50th Convention.
Sorry, I do not know where to find the diagrams but this should be sufficient. I hope to see lots of you in Straford-upon-Avon. Mark Kennedy
