This theme wasn't very difficult to come up with, essentially I took the default Casper theme, found a theme I liked on http://bootswatch.com and combined them into one. Regardless, I figure there might be people even less inclined to do a lot of work on setting up their blog with something other than a default theme. So I've put this theme up on github. You can grab it off of https://github.com/battlejj/super-casper and do what you will with it.
One thing I added was Disqus comments. A friend of mine mentioned "good idea to disable comments on threads." This wasn't a conscious choice on my part and there was no setting on in the Ghost dashboard to enable comments. So I baked in that capability. Setting it up should be fairly straight forward if you take a look at the README.
