Z-Squared Necklace
The signature piece for Tom Banchoff's 1996 artshow,
Surfaces Beyond
the Third Dimension, this image shows five views of the graph of
the complex squaring function, each from a different viewpoint in complex
2-space (or real 4-space). They are part of a sequence formed by rotating
the graph in four dimensions (or equivalently, walking around the graph).
The rotation is chosen so that, as a projection into a plane, the image
has three-fold rotational symmetry (the boundary curves form epi- and
hypocycloids of a circle).
Movies and a more complete discussion of the mathematics behind this image
are available at the virtual art exhibit. This surface is also the subject
of Z-Squared Tetraview.
