How to run the examples?

[coolaj86]

I tried this (to build):

git clone git@github.com:colinmeinke/wilderness.git
pushd wilderness
npm install
node bundle.js

And then this (to run the demo):

pushd examples/horse-triangles/
open index.html # opens in Chrome

That gave me this error in the JS console in Chrome:

Uncaught TypeError: Cannot convert undefined or null to object
