Great stuff. Is a video recording of this available online?
Hello @Hossein - thank you very much for your feedback 
- this is an infodeck rather than a slideument 
(https://martinfowler.com/bliki/Infodeck.html…) so sadly there is currently no video to go with it 
. I hope you still find it useful.
So sad. Maybe you’ll do one some day in near future?
maybe - thanks 
- the idea of the deck is that it is just meant to be read and should contain everything needed to follow - my presence should ideally be superfluous
I wouldn’t quite say so. Reading over lunch isn’t as pleasant to me as watching a video, after all. 
lunch? no, I agree with you. I don’t mind reading the newspaper while I eat, but I wouldn’t read a slide deck, not even mine!
