The Christie Grace presentation suffered from unreadable slides. I redid the slides (to dark, to save eyes), added subtitles, and a bit of video.
I included the references at the end.
This version should be shareable to people who will not read the .pdf.
I also have made a highly compressed .webm, with subtitles, that fits in 16MB and can be sent as an email attachment.
Unfortunately I do not currently have the ability to share optimized video here, as wtyl re-encodes my uploads to less efficient formats while also deleting the subtitles.
You may download the share-able .webm, with integrated soft-subtitles, and readable pdf slides here (16MB) https://0x0.st/HfCJ.webm
