This is the repo of the visualization software he demo'd. Not sure how accessible it would be to run locally, but I saw the demo in person and it was pretty cool: https://github.com/dollabs/planviz
It turns out that one of the A/V guys unplugged the laptop feed 5 min in and that's why the video is just talking heads.
I'm going to redo the demo and screen capture the video and splice it in somehow.
