This is exactly the sort of thing I like to listen to while driving. Thank you. I have a bit of driving to do today. :)
Edit: What a fascinating video. I was rather distracted when driving, listening to it (the roads were busier than I anticipated) - but I will be revisiting this video later today when I am back home again after the rest of my errands are complete - I'm hanging my exhibition as I write this, just waiting for ... some of the clients of the business it is being hung in to leave so I can get the last three images up in that corner of the cafe.
