The lipstick robot - A great way to explain Deep learning

I love motivational examples in teaching complex ideas! I use this simple little video to teach Deep Learning to my students. When we consider Deep Learning, we think of ideas like teaching a computer to recognize images of cats using Deep Learning OR training a computer to play pacman using Deep Learning. You let the Deep Learning system iterate with many examples and in each case, you tell the computer using a classifier if its interpretation was correct or not (aka is it a cat or not, Pacman scores, etc.) Now watch the video - video link is lipstick robot. I see the click at the end of the step as a classifier.
