Resize of scherka 36

Scherk's surface is defined by exp(z)cos(x)-cos(y)=0. If z is treated as a complex number rather than a real and multiplied by exp(it) the solution to Re(exp(z)cos(x)-cos(y))=0 performs this curious dance act. The color denotes the imaginary part.

 

This set works nicely as a slideshow.
