The object in the center of the green cloud was generated with a filter called "SolarCell" that I picked up from Flaming Pear Software. It's not free, but well worth the $20 shareware fee. You can download a 15 day demo from: http://www.flamingpear.com/download.html They have many other filters available, too, so check them out. The rest of the picture is a render from Bryce 4. The green cloud is a volumetric texture I cooked up and applied to a sphere. -Jim Moore
