I love how using training data from the Internet has resulted in the GANs believing that a picture of a "cat" often contains text -- or, at least, shapes resembling text -- at the top and bottom of the image. (Visible on the right side of the screen starting around 4:20.)
The interpolating animals look so much like my dreams it's unsettling. I often wake up when things get too "unrealistic" and people or animals are changing shape too rapidly. Whenever I see something come out of a NN that looks like something that came out of my brain I get a little future shock.
