This abstract sketch was created by a snail browsing on algae. The palate was the neglected glass on my greenhouse in the Chilterns, England. The seemingly random image pattern results from the snail's radula scraping green cells from the glass. Note the fractal features of this snail trail. A fractal is essentially a fragmented geometric shape that can be subdivided into parts, each of which is, at least approximately, a small-scale copy of the whole.
