Robert Fathauer makes limited-edition prints inspired by tiling, fractals, and knots. He employs mathematics in his art to express his fascination with certain aspects of our world, such as symmetry, complexity, chaos, and infinity. His artworks are created on a Macintosh computer.
Self-similar Knot No. 1
13" x 16"
Digital print
2009
A starting knot was created that possessed sufficient geometric regularity to allow iterative replacement of a portion of the knot with a scaled down copy of the knot. Three such iterations were carried out to obtain the knot shown here. The path of the strand, specified as a series of Cartesian coordinates, was smoothed out so that strand in the final knot curves gracefully, as opposed to being a series of straight line segments that change angle abruptly. The knot was constructed using the program KnotPlot and then exported to PhotoShop for touching up.
Self-similar Knot No. 2
13" x 13"
Digital print
2009
A starting knot was created that possessed sufficient geometric regularity to allow iterative replacement of a portion of the knot with a scaled down copy of the knot. This starting knot had nine crossings and was configured as a trefoil knot nested inside another trefoil knot. Six iterations were carried out in order to achieve the knot shown here. The path of the strand, specified as a series of Cartesian coordinates, was smoothed out so that strand in the final knot curves gracefully, as opposed to being a series of straight line segments that change angle abruptly. The knot was constructed using the program KnotPlot and then exported to PhotoShop for touching up.
Slot Canyon Abstraction No. 2
12" x 16"
Digital print
2009
This image was created by reflecting and overlapping four copies of a photograph of Lower Antelope Canyon, a sandstone slot canyon near Page, Arizona. Working in Photoshop, the levels of each color channel were adjusted separately in different regions of the image to heighten the value and color contrasts.
