I opened a ticket if you are so inclined. The problem defined is that there isn't a clear method for getting this running in a quick webpage hackup way. It's JavaScript, so it should just 'work' when I cut and paste, as long as I'm including a min file somewhere.

There appear to be a good number of dependencies in the terra.js file, which isn't explained on the page. I see something called lowdash and seedrandom in there, both of which I have never seen before and have no clue how to install. I simply want to cut and paste the examples as they are shown and get something working. I don't want to run a bunch of build processes for installing a bunch of third party libraries on my machine when all I want is to include it on a single page in my project!

Anyway, it looks really cool. Wish I could use it.
