Thats pretty nice too, thanks thoughtzone. If I get any more submissions I'll rotate them.
Would be better is the plasma stuff was shades of green though.
Also this doesn't fit the theme properly.
I think I have have found the problem though. If you click and save the default header the image is 1300x400 but Wordpress asks me to upload an image 900x200.
So if anyone else wants to take up the challenge try a 900x200 image please
