First, I have to thank Bryce and you for liking it and Bryce for posting it... and even tho I think I told her how I did it, and she could therefore tell you about it, Antonia, it's still my work, so let me try to remember. ;)

I did it using the Bryce5 3D-modeling software; the pyramid is the Mayan pyramid mountain object, a bit modified; water is water (can't remember which setting?); and the background lighting is "Armageddon Sunset", again a bit modified, to put the pyramid's front more into shadow...

Then, I just resized it in PSP8, and the way that the sky looks painted, as Bryce says, came about, when I was saving it into a gif, with reduced colors... but I liked the effect too, so I kept it.

And last, "Is there a second or third pyramid?"... well, I just saw someone using a winter pyramid for her property's background, and I thought it would be fun to try that out, too... so the answer is, yes, there will be. ;)
