Stickman How We Met - video powered by Metacafe
A cute animation on unusual canvases, sort of a viral campaign for Samsung mobile phones, I think. There was some discussion on a message board where I found it whether the animation was later added by computer, but apparently not: I went to the artists' website to learn that it took more than 3600 drawings with gel pens, markers and eyeliner (among other things) and four days' worth of photography.
Warning: Music.
