Lack of RAM. :( I have a pretty cool image going and both of my computers are chugging like an old locomotive going up the side of a mountain. I had to drop the idea of finishing it in Bryce because I caught a conversation between my two computers that they were figuring out a way to rub me out. So now I'm going to try some serious postwork in Photoshop and see if I can salvage this image. We shall see. More details soon. MD
