I'm a huge fan of Rory Sutherland. Occasionally i'll listen to his talks just for inspiration or to learn a simple way to say something complicated.
Often I have the lecture's on in the background, however I noticed this, while it was playing in YouTube.
It's the familiar Google maps navigation device.
Play with it in this video. Or even use your little grabby hand and move the video.
Oh my god, how cool is that?
It's a pretty awesome feature. Just in case it's not working for you, as you move the navigation icon, you move around the room. Perhaps this talk is not the most exciting use of this tech. However i'm looking forward to premier league games on YouTube next season.
