Update regarding the Svbtle theme.

I sent a tweet (https://twitter.com/lylemckeany/status/253688832501874689) to Dustin early asking about it. He kindly asked me to change my theme and I will in the next couple of days when I can get around to it. I thought/hoped that the Gravity on Mars developer(s) had his permission to create it, but that is definitely not the case.
