Caution: Sink the model so the first layer is not empty!
The moving sofa problem asks for the largest sofa that can pass a hallway with a right angle turn.
In 1968, Hammersley proposed this shape defined by segments and arcs with area 2.2074...,
while the conjectured optimal area is 2.2195....
Inspired by the 15-puzzle, I turn Hammersley's sofa into a gidget/keychain.
