A peek inside helps when trying to figure out what something is.

This one is almost creepy enough to be a Halloween image.

Creating this many pillars individually would have been impossibly complex. I instead made a solid block, with a grid of negative cylinders inside, carving out the archways.

When I started this rendering it was almost warm outside. As I worked, the weather grew colder and started to snow. I'm sure that was just a coincidence.

I worked on lighting this one for several hours. I finally ended up with lighting similar to what I started with, the trick was to keep the pinkish mist from affecting the light inside the dome.

I had put this one aside not expecting I would get anything decent out of it. Forgetting about it, I loaded it to see what it was and after extensive lighting experiments I found one of my favorite images.

This turned out to be much more difficult than I thought. I wanted it to be a view from inside an ant hill, looking down several tunnels at once. But since you can only point the camera one direction at a time I had to opt for a more cavernous approach.
