Is this actually useful? Has anyone tried it? The examples are quite simplistic. I would like to see a more full featured app or site before I invest any time into investigating it.
The entire site is written in Elm (excluding the code editor which relies on CodeMirror). If you click the "View Page Source" in the top right corner of every page, you can see the full source for it.
For example: http://elm-lang.org/edit/Examples.elm
Here's the [full source for the website](https://github.com/evancz/elm-lang.org/tree/master/public) and a [game of Pong](http://elm-lang.org/blog/games-in-elm/part-0/Making-Pong.htm...).
