I've been wanting to test some of org-mode's source block features in the build system. I've also been thinking about how poems often have multiple ways of reading them, in a rhythmic sense. So here are two versions of a rhythmic transscription of Invitation by Shel Silverstein, the first poem from Where the Sidewalk Ends.

I didn't pre-generate these images. The LilyPond source code is embedded in the post as and org-mode source block. During the site build process, the blocks are executed and the resulting svg is included in the exported HTML.
