Yeah, the whole thing is self-indulgent, maybe even a little creepy [in an earlier version of the movie, Facebook automatically selected a map showing where I live, followed by a picture of my house]. But when you see your own first draft, you'll want to start editing and tweaking. The video-app doesn't allow much customization, but the result is still kind of cool.
I uploaded this video because most people won't go through the initial clicking process until they see what one of these things look like [I used Snapz Pro to grab the video; any glitchiness comes from the conversion process]. So check out the video and then go get your own: http://www.timelinemoviemaker.com/
