A picture from inside the spiral staircase in the tower. I'll probably have to add some lights, but I liked the effect of the sunlight off of the wall. The current stair material is obsidian, but it will probably change in the future. Out the left window you can see the waterfall pool, and (faintly) the underwater skylight.
Mod: 3/7/07 New picture, this time with better global lighting.
