If you like animation, or humor, or TV, or insomnia, you're probably familiar with Adult Swim—but how much do you really know about it? Kaptain Kristian, a YouTuber who makes "visual essays," has created a wonderful documentary (more of a "visual love-letter," really) about the network-within-a-network's history and significance. It's only his second such documentary (the previous being about the gorgeous 1940s Superman cartoons), but this editor/documentarian has already racked up almost half a million views on his sophomore effort.
