Movie Description and Formats:

 This movie shows projections into three-space of the complex square-root relation, the inverse of the complex squaring function, as the surface is rotated in four-space.

The initial position projects into the x, u, u space, so this is the graph of the real part of the complex square-root relation. The final position is the projection into the y, u, v space, which is the graph of the imaginary part of the complex square root. The intermediate frames follow the rotation in the xy-plane that takes the y-axis to the x-axis.
