-This is one
of many hinged dissections of one regular polygon into another.
See Greg Frederickson's book, "Hinged Dissections: Swinging and
Twisting". The hinges are made out of brass.
-Greg Frederickson was interested
in my work, so I made him a
copy of my model. He supplied me with the dimensions.
