The dryades were beautiful tree nymphai -- ladies of oaks and pines, poplar and ash, apple and laurel. At their birth trees sprung up from the earth, trees to which their lives were closely tied. While the tree still lived, so did the Dryad, but when it died she died with it.
The dryade typeface is a font that grows as you type text. Letters are not the same as trees, but they have the same internal structure as trees. Because each letter is different, you might see a letter as a tree sort: (e.g. an oak or pine). Following this analogy, a font would represent a wood sort (such as fruit trees or aspen trees).
Dryade is currently two fonts: a 'conservative', geometric version, and a more correct, organic version. In the offline version, there is also a toolbox where you can design your own letter.
Note that letters are not spaced next to each other: A word is formed by 'branching': one letter produces the next one as a branch of itself.
