Looking for a Drupal 7 theme and this site demos two themes, Aperture and Reliance http://demo.sitefont.com/?theme=reliance

I located Aperture on the http://drupal.org/project/Themes but Reliance wasn't listed.

Is the Reliance available as a free theme? If so, is there a download link available? Or is it proprietary to SiteFont? And if proprietary, is there a similar free one?

Appreciate the help.

Thanks!
