A talk based on the paper
"Unexpected twists in geometric dissections", by Greg N. Frederickson:

Here are several pictures of me giving an invited talk at the Kyoto Conference on Combinatorial Geometry and Graph Theory 2007.

. . .

The picture directly above shows the {12/2}-star in the animation of my twist-hinged dissections of a {12/2} to a square. It's actually from a different paper, "The heptagon to the square, and other wild twists", but I showed a few of the animations from that paper right at the end of my talk.

Below is a picture of me (on the left) with Jin Akiyama (in the center) and Pavol Hell (on the right). This was one of many pictures taken at the conference banquet.
