Larsen, D. The Pines at Walden Pond, 2000. <http://www.deenalarsen.net/pines/>
The Pines at Walden Pond traces musings about Thoreau from the modern Walden Pond through a two-fold navigation: map and embedded texts.
This work uses Trellix, a software program that designed websites with map views that show nodal connections and pathways. The map here shows the thoughts branching down a pine. The map is a feature of the software, and each node can be dragged to show the nearly linear relationships (a one-to-one correspondance with link to node in the map view.) The Trellix map is highlights the current node in yellow.
The map view in The Pines at Walden Pond shows the structure of the work as lines of thought branching from a pine. This map structure is similar to, but more abstract than the clear pictures of Garnier Fructis  and Saturn  or even the scene from IDEO  .

Note that the embedded text anchors here range from words to phrases. The anchor on "have lost" emphasizes the past conditional more than if the anchor had been merely on "lost." Likewise, the anchor on "core of their being" emphasizes the "their" of the pines more than had the anchor been on the word "core" alone.
