If you wish to see some really amazing examples of Fractals in Nature, then you should head over to the "Armonia fractal de Doñana y las marismas" web site. (My Spanish is not too great, but I believe this means Harmony fractal of Doñana and the salt marshes.) http://www.ArmoniaFractal.com/ There are a lot of wonderful aerial photographs that show some great examples of what goes on in such places. And you may also be interested in the video at the bottom of the page, which is only 1 of the 7 that are available for viewing. I was turned onto this site by Terry Wright's recent posting on Orbit Trap <http://orbittrap.ca/?p=1316> that showed the image entitled "El árbol de agua" (The water tree), which was just one of several sites being presented.
