We can see anything; most of the presentation is a demo on the video panel.
We need an higher resolution to read the data.
I just checked the resolution myself and it's pretty hard to follow along. If you grab the code from GitHub  and maximize the video it might be bearable but I think we need to take action here. I am going to re-record the demo as screencast and post the link here as soon as it's ready.
Thanks for your patience!
