This theme is mc360 water
It has a custom background animation which looks like moving water which i was quite happy
with the way it turned out
I was thinking of changing the background images to the traditional purple,green, etc but don't know yet.
please check it out and tell me what you think
Also looks pritty good when you disable the whitewash with the animation running http://www.tintense.com/download.php?file=561
