Attached Link: Wet ground tute

Ok silly q possibly... but .. could you somehow shape a sym lat to look something like a rock and then try the route of something like terrain layering with different materials and blended tranparencies affected by altitudes?  Just a thought and probably way off the mark.. but interesting to ponder none the less.

also dont know if the link is of any use or not?
It says wet ground tute however it may give you smoe more ideas
