I was more focused on listening and making notes, than making dumb photos. I have one more, pic related.

Basically, the revolution will be the fruits of two independent projects - Kibble balance project, which will use the von Klitzing and Josephson constant to create a system, which will generate a force of pull equal to the one kilogram (taking into consideration the local value of g), and Avogadro project, that is trying to create a perfect sphere made out of countable number of silicone crystals. Both of those methods will be used to approximate the Planck constant up to around 10^-9 uncertainity.
