On January 7, 2007, I had a book signing at the A K Peters booth at the Joint Mathematics Meetings in New Orleans. I brought along six wooden models and two cardstock models for demonstrations. They were a big hit.
In the first photo, I'm holding the cherry-wood model of my dissection of a regular decagon to a pentagram. You can see someone's pair of hands manipulating one of the two assemblages for the cherry-wood model of my dissection of two pentagrams to a {10/3}-star. You can recognize other models lying on the top table surface that are from my wooden-models video.
In the second photo, the man in front is manipulating the cherry-wood model of my dissection of an ellipse to a heart. The woman in the background is manipulating one of the three assemblages for the cherry-wood model of three small hexagrams to one large hexagram. Now why was I so amused?
