On August 1, 2005, I gave an invited talk, "The Manifold Beauty of Piano-hinged Dissections", at Renaissance Banff: Mathematics, Music, Art, Culture, in Banff, Alberta, Canada. Although I had included lots of short video clips in my presentation, I thought that it would be fun to bring along a selection of some of my wooden models for demonstration. I left these on display on a table in the exhibition room, and stopped by every once in a while to encourage participants to "get the feel" of my models. Carlo Sequin took the following photos of some of my models.
Above on the left is a W-pentomino folded up into a square. On the right is a Greek Cross folded up into a square.
Above are the same figures as before, but folded halfway between the figures.
Finally, is the W-pentomino on the left above, but Carlo didn't get the Greek Cross on the right.
