This movie shows projections of the complex squaring function (over the
unit square) into three-space as the graph is rotated in four-space. The
initial position projects into the x, y, u space, so
this is the graph of the real part of the complex square function. The
final position is the projection into the x, y, v
space, which is the graph of the imaginary part of the complex square. The
intermediate frames follow the rotation in the uv-plane that takes
the v-axis to the u-axis.
