A side note: you embedded .mov videos inside <img> tags. This is not compatible with all browsers (notably Chrome and Firefox), which won't load the videos.
Minor usability comment: the screenshots are too small to be readable. Whenever that's that case in my blog posts, I make those screenshots clickable and add (Click to enlarge) below it, to make it easier for readers to see the image are original resolution. In markdown, I do that like this:
[ ](image_url.png)
(Of course, I can also right-click and do "Open image in new tab", but that's one click extra...)
Congrats on the awesome project, BTW! You were lucky that I wasn't sitting next to you on the plane. I would have wasted so much of your time asking dumb questions.
