I've built mathematical models ever since I read Hugo Steinhaus's
"Mathematical Snapshots" more than 60 years ago. Over time I graduated
from crude cardboard platonic polyhedra and soma cubes to some
constructions friends have graciously called art.

Steinhaus photographed the surprising hexagon that appears when you
halve a cube with a plane perpendicular to the long diagonal. His photo
inspired this four cube twenty four piece wooden puzzle and 3D printed
earrings. Can you see the hexagons? Stranger shapes emerge when you
slice into seven parts with six equally spaced planes not quite perpendicular
to the long diagonal to create a twenty eight piece for cube puzzle. You can
find out more and print your own at www.cs.umb.edu/~eb/slicecubes.
