A video of the talk should be online soon at: https://evolve.xamarin.com.
In the session, I presented a city rendered using SceneKit, from CSV data provided by a type provider. I've uploaded a modified version of this that simply uses a random function to position buildings.

One notable mention of the talk was Eric Sink:
"On Friday, Larry O'Brien (ed: and me! :) ) gave another fantastic session on F#. And I left with the even stronger impression that even though learning cool functional stuff is great, I don't have to be a functional pursit to benefit from F#."
I'm really glad that this was at least one of the takeaways from our talk. There's plenty of intimidating content out there from academia, and other functional programming purists. And for a long time this kept me away from really digging in. F# makes it really easy to start dipping your toes in the water ... especially when paired with Xamarin Sketches :)
