My wife came along and provided moral and iPhone video support so I've uploaded what we got to YouTube. It's not the best quality but I think it's decent enough to share, you can find the slides here. Might invest in a GoPro and a tripod if I end up doing more of these. Many thanks to Jess Telford for the photo.
In engine related news, I've finally finished the Encounter Designer tool which has taken a huge amount of time and effort, particularly on the React side of things as the data for this tool is quite complex. I should have a new post up soon, so watch this space!
