Is the dark version of the default theme available? 

I would love to see how it looks and what things I would need to do to have it customized for my website.

The logo would be the tricky part because it's kind of big, not humungous but if I'm looking at the size of my current logo and try to fit in this demo header, the logo will overlap where the word 'Portal' is. 

I've got time to figure that out.
I intend to create a dark version of the theme.

I think it's need only change colors from light to dark :x
