Putting together a click-along demo

After a while, you get good at it (usually), but that's not a very scalable model. There's only one of you, and, try as you may, it takes a long time to make more of you.

I wanted to have a live web demo app with a video explaining what the app does, but I was frustrated by the fact that I couldn't point things out in the app. Then it occurred to me that, actually, I could. The major video players have Javascript API's that can keep you informed of the video's progress. It's fairly easy, based on that, to use a bit of Javascript and jQuery to highlight specific portions of the app at specific times in the video.

Here's what I learned while putting this whole thing together."
