Big thanks to David, Peter and the team for inviting me to be part of this pilot, which I hope to see opened up to more of Tumblr’s design community soon. On that note, don’t miss my colleague Mike Harding’s delicious Scaffold theme, also for just $9.
Almost forgot: I’ve released National Park from my own site as well.
Update: there is now a version history page that lists new features, bug fixes and improvements to the theme.
