Designs and patterns in nature often fascinate me such as in the following photos from Peace Valley Park near Doylestown, Pennsylvania. In the past, I have used some of these types of designs as background images and patterns for web pages.
I love the patterns in tree bark and in this particular photo the morning sun shining brightly on the bark just magnifies the beauty.
Fungae on trees present a combination of curved patterns and slightly varying color contrasts.
This is actually the underside view of a fallen down tree stump. But I could actually imagine this as an upside down view of a topographical map for a selected terrain. Or it could also be a view inside a cave.
Sometimes the designs of above ground tree roots resemble flowing rivulets curving whichever way nature leads.
