exports.colordetermines the color of the surface.
The demo will only work in modern browsers with WebGL support so latest Firefox/Chrome should be ok with up to date graphics drivers, no internet explorer unfortunately. If your browser and drivers are not squared away it will probably crash.
Lots of stuff, but the most important tools are npm and browserify. I also used a bunch of different modules I've written over the past couple of months. The database backend is based on leveldb. Here is a listing from the package.json:

Hi, could you explain why you rated this application so low?

Actually the shapeways integration does work, but it does take a little while to process everything, and it also silently fails if shapeways decides to reject your model for any reason.
For example, here is the output from the test model on shapeways:
I agree though that the interface for this needs a bit more work, but I had a hard time getting DAT gui to work as I wanted for this purpose.
For me ShapeWays gave a 500 page and I got no warning from your UI. It's cool that it does work in some case though.
It's an impressive project.
Did you try watching the video?
Like any WebGL application you need to make sure that your graphics drivers are up to date and that you have the latest version of your browser. Have you tried updating/restarting and running it again?
