  • In Hinduism, the six-pointed star--comprised of two, "up" and "down" pointing triangles--is named Shatkona, and it signifies the union of male and female. This digital mosaic emulates the Moroccan zellige tradition of assembling complex geometric patterns from individual, hand-cut ceramic tiles: the artist assembled this hexagonal design by mirroring copies of a digital "tile" cut from her original photograph of American bittersweet vine's entwined branches and colorful autumn berries.

  • From the artist's "American Bittersweet" series, this 2nd-generation surface design emerged from repeating and mirroring a digital "tile" cut and copied from a previously completed "Bittersweet" matrix. Trellis filligree and circular motifs still depend on the bittersweet vine's curling, twisting branch and twig structure and berry ornamentation that create the optical illusions of lacy texture and geometric shape. Converting the image to black-and-white prior to tinting it minimized the berries' visual impact and shifted aesthetic attention to the woven vines. Image aspect ratio = 7 x 10 (28"x40" @ 300 dp)i

  • From the artist's "American Bittersweet" series, this tesselated digital mosaic suggests, when viewed at distance, a tartan plaid surface design in turquoise, brown, and gold hues. Closer study reveals dense fields of bittersweet berries, color-shifted from their natural state to resemble turquoise and lapis beads worked into intricate geometric patterns accented with gold-toned bittersweet vines.

  • From the artist's "American Bittersweet" series, this surface design exploits the bittersweet vine's curling, twisting branch and twig structure to create a delicate filigree matrix. On this ornate trellis hang clusters of autumn berries shaped like bead-studded bows or brooches. Colors present in the original photograph of a specimen bittersweet vine were transformed into a palette of blues, pinks, and yellows. Image aspect ratio = 12 x 9 (24" x 18" @ 300 dpi)
    bittersweet denim lace bows.jpg
  • From the artist's "American Bittersweet" series, this surface design exploits the bittersweet vine's curling, twisting branch and twig structure to create an ornate filigree matrix studded with clusters of autumn berries. In nature, these red, orange, and yellow berries contrast starkly with the vine's gray-black bark; in this image, color editing produced turquoise and blue hues that transform berries into semi-precious stone beads and gild the vine's wiry tendrils with gold...as if Mother Nature were a fine jeweler ornamenting the earthly wilderness with her arts and crafts. Image aspect ratio = 2 x 3 (12" x 18" @ 300 dpi)
    bittersweet bejeweled.jpg
  • From the artist's "American Bittersweet" series, this surface design emerged from tessellating a hexagon, manually assembled by tessellating a triangular photo segment, and then cutting from that matrix a rectangular digital "tile" that would permit orderly mirroring to produce a 4-side matrix. The bittersweet vine's curling, twisting branch and twig structure and berry ornamentation create the crystaline outlines and laciness of this image's six-pointed snowflake patterns. Converting the image to black-and-white facilitated recoloring it to suggest snow's affinity for blue light. Image size = 27" x 31" @ 300 dpi

  • Featuring an ornate botanical pattern of leaves and branches, this tesselated digital mosaic has been assembled from 16 iterations of a square "tile" cut from a larger digital photograph of manzanita bushes growing in a forest on the eastern slopes of California's Sierra Nevada mountain range. This image, in contrast with its companions in the "Manzanita" series, displays the primary pattern that its "digital 'seed' tile" created with simple horizontal and vertical mirroring across a canvas. When a first matrix displays visual complexity, as this one does, that produces pleasing instances of pareidolia--optical illusions of faces, creatures, and other meaningful shapes--I play with color, shape, and line matches along offset edges of paired and clustered tiles edges to find alternate mosaic designs.
