Möbius Flow, Dawn Hahnemühle German Etching Print

A transformation of a surface is "conformal" if at each point the transformation preserves angles. (In a bit more detail, if we pick an arbitrary point and pick two curves meeting perpendicularly at that point, then the image curves meet perpendicularly, and with the "same handedness" as the original curves.) The most obvious conformal transformations also preserve lengths, such as translations and rotations of the Euclidean plane. (Reflections preserve perpendicularity, but "reverse" handedness, so are not conformal in the sense meant here.)

A conformal transformation of a sphere is a "Moebius transformation." It might appear that all Moebius transformations are rotations, but in fact there are many others. The spiral curves here are "flow lines" of a "one parameter group" of Moebius transformations.

All our prints are available on a range of matt and lustre finishes, each carefully profiled for fantastically accurate and consistent reproductions using giclée printing techniques.
