I found this example of visual definition in the October issue of Real Simple. This is an article titled "What's Really Aging You?" The subtitle explains that your skin is fragile, like these tulips that are in vibrant bloom at the beginning of the article. The caption explains that they were shot over a period of 40 days, showing the deterioration of the delicate bouquet which signifies the withering of your physical youth. Although we once may have been robust, strong, and beautiful floral specimens, we can eventually look forward to developing into droopy, wrinkly, empty bits of shrubbery. Fortunately, unlike these tulips, your skin regenerates itself as fast as every 28 days. So I guess there is a silver lining.
