weird this was posted 28 minutes ago and you posted nice video 2 minutes later
sounds cool were it not for the fact that the video is 38 minutes long

just saying...

i have watched the video and it is indeed very interesting although by listening to this guy and then the ones that ask the questions I realise that I really know almost nothing on this. (and guessing the math and programming skills involved probably i never will)
But even without all the math you can get the gist of it
