Updates to Chapter 10, "Elation in Tessellations",
in Hinged Dissections: Swinging & Twisting, by Greg N. Frederickson

And no abuts, please

I delivered the manuscript to the publisher at the end of June 2001, and then the race was on to see how long it would take to find an improvement that was too late to make it into the book. The honor was won in July with an improvement to the swing-hinged dissection of a dodecagon to a square. Unlike the dissection in Figures 10.17 and 10.19, the dissection below has no abutting hinges.
