This appears to be connected to François-René Rideau's TUNES project (http://ngnghm.github.io/talks/cc-lc2016.pdf). These slides are probably worthy of a submission themselves.
In the meantime, there is a bad recording of an earlier take on the same ideas from LispNYC. The talk at LambdaConf was definitely better delivered, though. https://vimeo.com/155517248 http://www.meetup.com/LispNYC/events/224215944/
