Worked on demo, tired, progress incomplete.

I was really tired yesterday so I just rested, but today I hope to put in at least an hour.

Let's try to achieve this today:

• add "try the demo" to landing page
• demo should be short and in browser

Gave it my best, but didn't manage to finish. Got pretty close, though - I just have to resolve some UI issues. Maybe tomorrow? Hopefully over the weekend I can set up some ads to run for the next week.
