Every year there's something in the Japan Media Arts Festival's Entertainment Division which also happens to be animated, and worth a mention. (The categories are porous like that.) This year that honour goes to the music video for Ryukyudisko's "Nice Day."
The entire video is a progression of still photographs starting somewhere in the 1970s, with a couple getting busy under the covers and producing a young boy. We watch him get older, get a job, and then he hits the clubs and meets a girl–and the whole starts going into reverse, as we go back into the girl's history. However, we find ourselves going back even farther than her parents, for reasons that eventually become apparent—and the eventual trip forward again carries its own surprises.
There's a lot of whimsy in this video, and the pity of the Flash-based video above is that you lose some of the detail in the historical photos, as well as the deliberate colour choices to replicate older film (up to a point—director Junji Kojima skimps a little when he starts getting into the 1930s and earlier).
By the way, if you think the tune is catchy you can drop a couple of sawbucks for an import of the single at Amazon.
