At the Edge

"My love of dendritic patterns led me to discover Dann Blackwood and his photography when I was seeking a slide version of a computer-modeled aerial
image of the Mississippi River, because it mimicked the fractal patterns
of the Indian Ocean sea mud glaze I was using on my pottery. Dann
surprised me by including an extra slide, this “At the Edge” image...a gift
from one pattern lover to another. As our book, Centered On the Edge, began
to take form, I intuitively knew this photo was to be its cover image."
