How do you make this?

This site is generated as static HTML via Middleman, and the source is available on GitHub.

Search is kept local thanks to lunr.

When I publish to a specific git branch, Travis CI builds the site and deploys to Amazon S3. Cloudfront serves it to you.

Body type is set in ITF Poppins.

Other external resources are referenced, including Twitter’s scripts for explicit pop-ups and jQuery from their CDN. On the homepage a Flickr script is loaded which insists on loading a Yahoo geolocation script as well as requested assets. None of these should be using this to track you, but my control is limited so YMMV.
