A live demo of Sonar code base should be available online

I think it would be great to have a live demo of Sonar on the website, based on the source code for Sonar. I've occasionally wanted to demo Sonar to colleagues, but I didn't always have a runnable environment on my system.

As a side effect, it could make for an interesting test of stability

This might force you to implement a viewable version of the interface, where the options cannot be changed. But don't let that stop you: having the demo live, even if half-broken, would be really nice.
