I've been fiddling with this one for a while.
I don't understand what the two objects are in the air. It is also hard to figure out the water and the sands at first. Perhaps the water is too white?
This is so alien, it is hard to grasp where you are intending to go/be with it. :(
Sorry I can't be more specific.
That's alright - it's meant to be alien! It's kind of a showcase for some weird objects, plus the surfacing.
This is rather interesting. Are those crystals on the left half of the picture?
Not crystals as in plural - it's one object with some light displacements plus an image map shader for colour.
