Radiolab is back with another excellent video, produced by Everynone (click that link to view a bunch of similar videos). This video takes a simple approach: present a split screen with symmetrical (or complementary) items shown in each. By comparing people, food, animals, clouds, and all sorts of other interesting pairings, the viewer is challenged to figure out the connection between the two frames, and have a little moment of delight. Beautiful and calming, except for the last scene, which might be disturbing to sensitive viewers. I didn't have a problem with it (this is all staged), but -- fair warning, the last one is a doozy.
