Title: Geodes - beautiful and kinda 3D Mandelbrot-esque! Post by: twinbee on November 28, 2010, 04:20:29 PM The intricate crystal-like innards of Geode (http://en.wikipedia.org/wiki/Geode) is a wonderful thing to behold, even if the below shot is more than slightly reminiscent of Jaws! I can imagine a crystalized version of the real 3D mandelbrot set (if it exists) to look a bit like this inside, but far, far better still.

Here are some other fascinating images (the cream of the crop after searching Google images for "Geode"): http://www.wegnercrystalmines.com/22/imagesmf/JUNE%2006%20WEBSITE/Urg.%20Amethsyt%20Geode.JPG http://www.neatstuff.net/avalon/texts/KellieGeodeLG.jpg http://www.gamineral.org/_pictures/t07-jgmw-geode.jpg http://www.durangobill.com/GeodeCathedral.jpg http://www.freewebs.com/mysticallinks/AMethyst%20Geode.jpg |
