The impressive talk/demo that Boyd Multerer gave of it at ElixirConf will probably be up here later today: https://www.youtube.com/channel/UC0l2QTnO1P2iph-86HHilMQ/vid...

EDIT: It's already up! https://www.youtube.com/watch?v=1QNxLNMq3Uw

Boyd's former claim to fame is being Mr. Xbox Live @ Microsoft.

I put ElixirConf on my calendar just for this talk, and what he unveiled exceeded my already-high expectations!
