These are Rheotomic Surfaces – from the Greek

Rheo – flow


Tomos – cut or section (as in tomography)

The horizontal sections of these surfaces correspond to the moving equipotential lines of a 2D Laplacian flow, with height mapped to time. Such surfaces are complete, embedded and walkably connected.

Potential Flow


The hyperbolic paraboloid is not a minimal surface, but several people (including Chuck Hoberman) make the mistake of saying it is (more…)
