That screenshot shows i3 running. So it's mostly there. The bottom bar is showing though - need to get rid of that. And the terminal doesn't seem to be running - need to fix that.

Either of those lines should work since index.js is right in your home folder (the canonical one's a bit 'better', it'll still work if i3 or node decide their current working directory is not home).

That screen is so cute  :-$

I'm going to test some things and then post again.
