Looks interesting but did anyone get the demo to work?
Click on the "live demo" link, quite a long delay (few minutes), finally terminal-like display appears with "$" prompt.
However entering usual unix commands, ls, cd, etc., gives error: "Error while executing /usr/bin/ls: TypeError: get length method called on incompatible Object", or "/usr/bin/cd: command not found".
Running with FF Nightly. Don't know if it's me, FF, or the app.
What am I missing?
