Here is a WP that I made on POVRay too.
It depicts a futuristic shrine made entirely of glass with the red crystal sphere being the main diety (it represents the earth,I suppose).
If u look real closely, you will see the reflection of a tree shedding its leaves in the top left hand, hence the name.
Hope you like it.
