That Thingy looked very different in the previews ... funny, I never testrendered the bottom of it.
And going for the final render I just felt like killing the height-driven perlin-displacements (by Efflux).
So I was quite surprised how it looked like finally - and I was waiting quite a while to upload it.
Well, it is in my 'Junk-Thread', isn't it ,-)
Thanks for the critiques :-D
